Question

Jim has a bag of marbles. In the bag are 12 red, 10 blue, 15 white, and 13 black marbles. Without looking he pulls a marble out of the bag. What is the probability he pulls a white marble? Enter your answer as a decimal.

Answer 1

0.3

Explanation:

In the bag are 12 red, 10 blue, 15 white, and 13 black marbles.

So total = 12 + 10 + 15 + 13 = 50 marbles

The probability he pulls a white marble = 15/50 = 0.3
