What would we like to know? We went on to simplify the expression By relating this combinatorial representation to the binomial expansion, we can solve the problem.

Another way to look at this question is to consider each term of the expansion to contain factors a,b,c,d in various amounts, but always getting six factors in all. Alternatively, we could use the formula for counting distinguishable permutations. I think we can readily convince ourselves that there are 20 ways.

The general result is that tells us the total number of possible ways to arrange n objects when we have from 0 to n of the first type of object and n to 0 of the second type of object.

Think of the 10 cards as a family of 10 children, and think of a card selected by Seth as male and a card not selected by Seth as a female.

Each term will have one or more of the factors a, b, c, or d. I can tell you that the first possible sequence might look like this: We can also look at the possibility for each card: What is the probability that the sequence of 8 tosses yields 3 heads H and 5 tails T?

From a total of six letters, we choose 2 that are a, 2 that are b, 1 that is c, and 1 that is d. We can think of choosing note that choice of word!

The first possible sequence might look like this: How many arrangements are there of the 20 people that involve 0 people ill? Expressed in relation to "words" with arrangements of six letters, we might ask: We concluded that for a family with n children, k of them sons, there are C n,k different birth order arrangements.

Now, when counting the number of sequences of 3 heads and 5 tosses, we need to recognize that we are dealing with arrangements or permutations of the letters, since order matters, but in this case not all of the objects are distinct. We seek to generalize the counting strategies developed for binomials so that we can answer the same questions for multinomial expansion.

Can you imagine enumerating all possible outcomes? Total Possible Arrangements One of the very first questions we posed that explored this situation was about children in families: Create a counting problem for which 9! What patterns do you see in these representations? Given n objects with: There are at least a couple different ways we can think about this.

Click on the highlighted word to take you to a possible solution or hint for that problem.Feb 17, · Permutations Involving Repeated Symbols - Example 1.

In this video, I show how to calculate the number of linear arrangements of the word MISSISSIPPI (letters of the same type are indistinguishable).

Practice 4: The letters of any word can be rearranged. Carol believes that the number of different 9-letter arrangements of the word “TENNESSEE” is greater than the number of different 7-letter arrangements of the word “VERMONT.”. Oct 01, · These combinations questions ask about the number of arrangements of letters in words while giving certain constraints and conditions.

in-how-many-different-ways-can-the-letters-a-a-bhtml. 5 Letter Arrangements of the word 'Statistics' Ask Question.

If all five letters are different (which happens when you use one of each), you get $5!=$ words. How many different/unique $4$-letter arrangements are there of.

In poker, a 5-card hand is called two pair if there are two cards of one rank, two cards of another rank, and a fifth card of a third order of the cards doesn't matter (so, example, QQ and 68QQ6 are the same).

Transcript. Example 16 Find the number of arrangements of the letters of the word INDEPENDENCE. In how many of these arrangements, Finding total number of arrangements In word INDEPENDENCE There are 3N, 4E, & 2D, 1I, 1P & 1C Since letters are repeating so we use this formula!
