INDEPENDENT EVENT Occurrence of one event that has

no effect on the probability that a second will occur

Erika rolls a 2 on one numbered cube and a 3 on another numbered cube

DEPENDENT EVENT Occurrence of one event that has

an effect on the probability that a second will occur

Tom chooses some one for her team from a group of students and then Juan chooses and another student from the remaining students.

HOW TO SOLVE INDEPENDENT EVENTS P(A and B) = P(A)*P(B) Find the theoretical probability of

flipping a coin and rolling a dice.

* =

HOW TO SOLVE DEPENDENT EVENTS P( A and B) = P(A) * P(B after A) Draw a red marble from a bag of

2 red and 3 blue, then without replacing it drawing another marble.

What is the experimental probability that both marbles are red?

*= simplify

TREE DIAGRAM FOR DEPENDENT EVENT The tree diagram shows the

probability for choosing 2 red apples and 1 green apple.

Find P( red, then green)

*=. Simply

P(red, then red) =?
