Question

A bag contains 3 red marbles, 4 blue marbles, and 5 white marbles. What is the probability of pulling out first a red, then a blue marble if none are replaced

7/132



1/11



12/23



7/23

Answer 1

you have a total of 12 marbles, then the probability P(red) = 3/12

Answer 2

now the total is 12-1red = 11, then the P(b) = 4/11

Answer 3

multiply these probabilities 3/12 * 4/11
