9-7Independent and Dependent Events 9-7 Independent and Dependent Events (pg ) Indicator: D7

Compound event-Compound event- 2 (or more) simple events Independent events –Independent events – The outcome of the first event does not effect the outcome of the next event. P(A&B)= P(A)P(B)Example: P (rolling “5” and tails)=

Dependent Events- Dependent Events- the outcome of one of the events affects the outcomes of another event. P(A & B)=P(A) P(B following A) Example Example: P (queen and 3)= or 0.6%

You Try 1)Tossing 4 coins and getting heads on all four? 2)There are 10 country CD’s and 15 rock CD’s. What is the probability of drawing a rock then a country CD?

Mutually Exclusive eventsMutually Exclusive events: Can not happen at the same time or P(A or B) = P(A) + P(B) P(2 or 3 on a dice)= or
