A basket contains 6 red balls, 5 blue balls, 3 green balls and 6 yellow balls.

a) If a single ball is drawn randomly from the basket, what is the probability that it is
green?

1 answer

In total, there are 6 R + 5 B + 3 G + 6 Y = 20 balls.

There are 3 greens in the 20 total.

The chance of the first ball drawn randomly being green is 3 / 20

By the way.

3 / 20 = 3 ∙ 5 / 20 ∙ 5 = 15 / 100 = 15%
