Question

A bag contains 4 red, 2 blue, 6 green, and 8 white marbles. What is the probability of selecting a white marble at random from this bag, not replacing the marble, and then selecting another white marble? Round your answer to the nearest tenth of a percent if necessary.

Answer 1

14.7

Explanation:

So first you add all the marbles together, which equals 20.

-you the put 8 over 20= 8/20

Next you subtract one from the eight and add it all together again= 7/19

The equation should look like

-(7/19)·(8/20)

This would equal .147

simplified to 14.7
