1
Find permutations using permutation notation and using technology.
2
Determines how many possible orders of objects An arrangement of objects in a specific order ◦ Order is important! EX: In how many different orders can you watch 3 movies?
3
When one event does NOT affect the outcome of another they are independent. You can use the Multiplication Counting Principle to find the number of outcomes when events are independent. ◦ If there are m ways to make a first selection and n ways to make a second selection, then there are m ∙ n ways to make both selections. EX:5 shirts and 8 shorts, how many possible outfits? ◦ Shirts and shorts are independent of each other so there are 5∙ 8 = 40 possible outfits
4
When events are dependent and occur without repeating you can use a permutation. Ex: how many different batting orders can you have with 9 players? You can have 9 ∙ 8 ∙ 7 ∙ 6 ∙ 5 ∙ 4 ∙ 3 ∙ 2 ∙ 1 = 362,880 possible orders Or 9! which is read “9 factorial” n! is used to calculate a permutation. ◦ It is the product of all the integers from n to 1. ◦ Keep in mind that the value of 0! is 1
