1 CCGPS Geometry UNIT QUESTION: What connection does conditional probability have to independence? Standard: MCC9-12.S.CP.1-7 Today’s Question: What is the difference between the intersection and the union of 2 events? Standard: MCC9-12.S.CP.1, 7

2 A compound event combines two or more events, using the word and or the word or. Compound Probability

3 If two or more events cannot occur at the same time they are termed mutually exclusive. They have no common outcomes. Overlapping events have at least one common outcome. Mutually Exclusive vs. Overlapping

4 P(A or B) = P(A) + P(B) Mutually Exclusive Formula

5 OR Means you ADD

6 Find the probability that a girl’s favorite department store is Macy’s or Nordstrom. Find the probability that a girl’s favorite store is not JC Penny’s. Example 1: Macy’s0.25 Saks0.20 Nordstrom0.20 JC Penny’s0.10 Bloomingdale’s0.25

8 When rolling two dice find P(sum 4 or sum 5) Example 2: 123456 1 234567 2 345678 3 456789 4 5678910 5 6789 11 6 789101112

9 Deck of Cards 52 total cards 4 Suits 13 cards in each suit 3 Face cards in each suit

11 In a deck of cards, find P(Queen or Ace) Example 3:

12 P(A or B) = P(A) + P(B) – P(A  B) Overlapping Events Formula

13 Example 4: Find the probability that a person will drink both. A = drink coffee B = drink soda

14 Find the P(A  B) A = band members B = club members Example 5:

15 In a deck of cards find P(King or Club) Example 6:

16 Find the P(picking a female or a person from Florida ). Example 7: FemaleMale FL84 AL63 GA73

17 When rolling 2 dice, find P(an even sum or a number greater than 10 ). Example 8: 123456 1 234567 2 345678 3 456789 4 5678910 5 6789 11 6 789101112

18 Find Example 9: Complementary Events

19 Example 10: Complementary Events A = plays volleyball B = plays softball What is the probability that a female does not play volleyball?
