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) =?
