Question

Eight white balls and twenty black balls are in a bag. What is the probability of the drawing a black ball in one draw?

Answer 1

20/28 which is about 71%

Explanation:

so first you add up how many balls there are. 8+20=28. So 28 is the denominator for the fraction. there are 20 black balls, so that is the numerator. so 20/28 is the fraction. then you divide 20 by 28 to get the rounded percent.
