Question

A bag contains 3 red marbles, 7 blue marbles and 4 green marbles. If three marbles

are drawn out of the bag, what is the probability, to the nearest 10th of a percent, that
all three marbles drawn will be blue?

Answer 1

Answer: 50%

Explanation:

Total marbles: 3 + 4 + 7 = 14

Probability of picking a blue marble = 7 / 14 = 1 / 2

There is 50% probability of picking a blue marble.
