Question

A box contains 18 large marbles and 10 small marbles. Each marble is either green or white. 12 of the large marbles are green, and 5 of the small marbles are white. If a marble is randomly selected from the box, what is the probability that it is small or green? Express your answer as a fraction or a decimal number rounded to four decimal places.

Answer 1

Explanation:

total

18 large 10 small 28

-12 large/green -5 small/white -17

Remaining 6 large/white 5/small/green 11

Total green = 17

Total white = 11

Small = 10/28 = 5/14 = 0.3571

Green = 17/28 = 0.6071
