P(A) = number of ways for A to occur total number of outcomes. for theoretical probabilities. So far the problems we have looked at had rather small total number of outcomes.

Jan 14, 2023 · The calculation starts at n n (which is 10) and you multiply r r (which is 3) descending numbers, starting from n n. You could have also used the Fundamental Counting Principle (Equation 6.4.2 6.4.2): 10––– ⋅9– ⋅8– = 720 10 _ ⋅ 9 _ ⋅ 8 _ = 720. There are 720 different ways for cars to finish in the top three places.
Oct 9, 2023 · A quicker way to calculate the number of final outcomes when provided different options for at each stage of choice is to multiply together the number of options at each stage. We can use multiplication to calculate the number of different design packages that Gretchen can consider: \(2 \times 2 \times 3 = 12\) design packages.
You can also look at this in a tree diagram: Figure 4.4.1 4.4. 1: Tree diagram. So, there are 6 different “words.”. In Example 4.4.2 4.4. 2, the solution was found by find 3 ∗ 2 ∗ 1 = 6 3 ∗ 2 ∗ 1 = 6. Many counting problems involve multiplying a list of decreasing numbers. This is called a factorial.
Upon completion of this lesson, you should be able to: Understand and be able to apply the multiplication principle. Understand how to count objects when the objects are sampled with replacement. Understand how to count objects when the objects are sampled without replacement. Understand and be able to use the permutation formula to count the ...
Such techniques will enable us to count the following, without having to list all of the items: the number of ways, the number of samples, or; the number of outcomes. Before we learn some of the basic principles of counting, let's see some of the notation we'll need. Number of Outcomes of an Event. As an example, we may have an event E defined as

We can determine a general formula for \(C\) by noting that there are two ways of finding the number of ordered subsets (note that that says ordered, not unordered): Method #1. We learned how to count the number of ordered subsets on the last page. It is just \(_nP_r\), the number of permutations of \(n\) objects taken \(r\) at a time. Method #2
