Question

Find the probability of this event. Enter the answer as a fraction in simplest form, as a decimal, and as a percent.

You choose a marble at random from a bag containing 12 red, 10 blue, 6 green, 10 yellow, and 22 black marbles.

The marble is red

Answer 1

20% probability of a red

Explanation:

How many marbles are there total?

12 + 10 + 6 + 10 + 22 = 28 + 32 = 60 marbles

P(red marble) = 12 red/ 60 total marbles = 12/60 = 1/5 = 20%
