Question 1115053: whenever Suzan sees a bag of marbles, she grabs a handful at random. She has seen a bag containing three red marbles, four green ones, three white ones, and two purple ones. She grabs five of them. Find the probability of the following event, expressing it as a fraction in lowest terms.
She has two red ones and one of each of the other colors. Answer by math_helper(2461) (Show Source):
You can put this solution on YOUR website! P = P(2Red+1Green+1White+1Purple) = (# of ways this can happen) / (# ways of selecting 5 marbles)
Total marbles = 3+4+3+2 = 12
# ways of selecting 5 from 12: 12C5 = 792
