Question

A bag contains 4 gold marbles, 6 silver marbles, and 22 black marbles. You randomly select one marble from the bag. What is the probability that you select a gold marble?

Answer 1

1/8

Explanation:

first we have to find out how many marbles there are in total

this can be displayed as

4+6+22=32

there are 4 gold marbles, so the probability is 4/32

this can be simplified to 1/8

1/8 as a percent is 12.5%

so

1/8 or 12.5%
