Emma's Dilemma
Introduction and Planning The problem set involves investigating the number of different arrangements for different amounts of letters. One arrangement is: EMMA A different arrangement is: EAMM Another arrangement is: MEAM I am going to investigate the number of different arrangements for the letters in the name EMMA. The name EMMA consists of 2 different letters and 2 letters the same. I am going to investigate other names with the same combination of letters; I will try and find a formula for these combinations I will then look at the name LUCY. This combination consists of all the letters being different. I will also try and find a formula for this arrangement, and number of letters. EMMA, AMME, AMEM, EMAM, AEMM, EAMM, MMEA, MMAE, MEMA, MAME, MEAM, MAEM. There are 12 possibilities; note that there are 4 total letters and 3 different. What if they were all different like Lucy? Arrangements for Lucy: 2 Lucy, ucyl, cylu, ycul, Luyc, ucly, cyul, yclu, Lcuy, ulcy, culy, yulc, Lcyu, ulyc, cuyl, yucl, Lyuc, uycl, clyu, ylcu, Lycu, uylc, cluy, and yluc. There are 24 different possibilities in this arrangement of 4 letters all different. Double the amount as before with Emma's name, which has 4 letters and 3 different. I have noticed that with Lucy there are 6 possibilities beginning with each different letter. For example there are 6 arrangements with
Emma's Dilemma
Emmas Dilema Jonathan Busby This piece of coursewrk is to investigate the possible arrangements of Lucy and Emma. Also I have to investigate the number of different arrangements of various groups of letters. I will start my experiment off by investigating the two-lettered word JO. Two-Lettered Word JO OJ JO has a total of two letters making up its word. Therefore its total amount of arrangements is that of tom. Three-Lettered Word TOM, TMO, MOT, MTO, OMT, OTM I have a three lettered word (tom) which has a total of 6 different arangements, as i have shown above. Four-Lettered Word LUCY UCLY CYLU YCLU LUYC UCYL CYUL YCUL LYUC UYLC CULY YUCL LYCU UYCL CUYL YULC LCYU ULYC CLYU YLUC LCUY ULCY CLUY YLCU By arranging the letters in this way, I found that the four-lettered word LUCY had a total of 24 arrangements. By showing how many arrangements there were when the single letter L was at the beginning I could calculate the total amount of arrangements for the three remaining letters U, C And Y. If I then multiplied the number six (number of arrangements) by the number four (total amount of letters in the word) I could calculate the
Emma's Dilemma
Emma's Dilemma By Sophie Morand I'm going to investigate the number of ways the letters in the name Lucy can be arranged. I will do this systematically by finding all the different arrangements beginning with L, then beginning with U, then C, then Y. LUCY LUYC LCUY LCYU LYCU LYUC ULCY ULYC UCLY UCYL UYCL UYLC CLYU CLUY CUYL CULY CYUL CYLU YLCU YLUC YULC YUCL YCLU YCUL Including "Lucy" there are 24 arrangements of the letters L U C Y. I am going to use the same systematic method to investigate the arrangements of Emma. This name is different to the name Lucy as in Emma there is a double "m" and in Lucy no letters are repeated. EMMA EMAM EAMM MMAE MMEA MEAM MAEM MEMA MAME AMME AMEM AEMM Including "Emma" there are 12 ways of arranging E M M A. I am now going to investigate the number of ways a four-letter word with one letter repeated three times can be arranged. I will use the letters E M M M EMMM MEMM MMEM MMME There are four ways which the letters E M M M can be arranged, including "Emmm." A four-letter word with one letter repeated four times has only one way it can be arranged, for example MMMM has no other arrangements. I have organised my results in a table. From looking at the results in my table I can see a pattern When there are no letters repeated, like in Lucy, there are 24 arrangements. In a word with 2 letters repeated, such

Emma's Dilemma
Introduction Emma's Dilemma is about how many times a name or group of letters can be re-arranged. Firstly I will start by re-arranging the name 'Lucy.' I will state all the possible ways of re-arranging 'Lucy.' I will also find a formula for it. Secondly I will re-arrange the name 'Emma' and state the different re-arrangements. I will also find a formula for it. I will then use a different set of letters and names and find out how many times they can be re-arranged using a formula I create for it. Lastly, I will make my coursework harder by using words, which have more than one of the same letters, e.g. Mississippi. I will re-arrange AAB and then move on to more complicated ones like AABBCCDDEE. I will find a formula that relates to them as well. Hypothesis I think that the more letters there are, the more re-arrangements there would be whether there is more than one of the same letters. For e.g., when re-arranging a two-letter word, there will be two arrangements. Then, if I re-arrange a three-letter word there will be more re-arrangements due to the larger number of letters. > I will start by finding out how many times 'Lucy' can be re-arranged.

There is a quicker solution to this problem. All that you need to do is (If you need a 4 letter word) you would do 1x2x3x4. If you needed 5 letters you would do 1x2x3x4x5 and so on. If you want to find out the value of the repeated letters field you would then just divide it by 2. I predict that a 5 letter word will have 120 combinations because 1x2x3x4x5 = 120. 20 combinations will be too much so I will do a 5-letter word that has a repeated letter such as Barry Larry or Annie. This will, according to my theory
Emma's dillemma
Introduction: In this coursework I will be investigating "Emma's dilemma" which is about permutations of letters. I will see how many permutations of the word "Lucy". Then I will continue my investigation by finding the amount of permutations in a word that has 2 letters the same such as the word "Emma". In order to fully understand the work and find patterns between the words and arrangements, I will need to structure it to show how I got from one point to the other. To further my investigation I will see how many permutations there are in various groups of words such as, words that have 3 letters the same and the rest different, and I will expand on this theory to find patterns relating to the work. Part 1: For the first part of this investigation I will be finding out how many permutations there are in words that have all the letters different. I have decided to use A, B and C to make up a 1 letter word, 2 letter word and a 3 letter word such as A, AB and ABC. A is a one letter word that has only one permutation = A AB is a two letter word that has two permutations = AB and BA ABC is a three letter word that has six permutations = ABC, ACB, BAC, BCA, CAB and CBA. "Lucy" is a four letter word that has all the letters different in it. By working out how many permutations of the word "Lucy" I will be able to notice a pattern between words that have all the letters

I have written them out in sets with Set 1 beginning with L. Set 2 with U, Set 3 with C and Set 4 with Y. in each set the arrangements are written out in an order i.e. in set 1 the first 2 arrangements begin with LU, the 2 after that begin with LC and the 2 after that begin with LY. There are 24 different arrangements. Examples If it is just one letter then you cannot change it. If it is two letters like AB then it can be changed into AB or BA and there are 2 arrangements. If there are three letters like ABC then there are 6 arrangements. I organized this so that set 1 begins with A, set 2 with B and set 3 with C.

Emmas dilemma
Investigation I am first going to write out all the combinations for the name Emma. emma eamm emam meam maem mmea mmae mema mame amme aemm amem This proves that if a name has the same arrangements of letters they will have the same total number of different combinations. However, this does not give me sufficient information to develop a formula. I am now going to look at names with 2 letters the same like Emma, but with a different total number of letters. I am going to look at all the combinations for the name Lucy. Lucy has 24 different combinations. This means that all names with 4 different letters will have a total of 24 different combinations. I am now going to look at different names with different numbers of letters. All the names I investigate will all have different letters. Name: Jo Total number of letters: 2 jo oj Jo has 2 different combinations. Name: Ian Total number of letters: 3 ian ina ani ain nai ain Ian has 6 different combinations. I have realised that the total number of combinations is the number of letters multiplied by the previous number of combinations.
