Question

A bag contains 5 red marbles, 10 white marbles, and 9 blue marbles. You draw 3 marbles out at random, without replacement. What is the probability that all the marbles are red?

Answer 1

5/24

Explanation:

• Number of red marbles = 5

• Number of white marbles = 10

• Number of blue marbles = 9

• Total number of marbles = 24

• P(getting red marbles) = (Number of red marbles)/(Total number of marbles)

• P(getting red marbles) = 5/24
