How can we use theoretical probability to predict experimental probability? Question of the day
agenda • Go over workbook p. 503 • Notes on independent vs. dependent events • Partner exercise from workbook • Workbook p. 507-512 • Exit ticket
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) =?
