Question

Ajar contains a mixture of 10 black balls, 8 red balls, and 2 white balls all the same size. What is the probability of

drawing either a red, black, or white ball in one draw?

Answer 1

The total number of balls = 10 + 8 + 2 = 20 balls

probability of black balls = 10/20 = 50%

probability of red balls = 8/20 = 40%

probability of white balls = 2/20 = 10%

the three probabilities:

probability that the ball is one of the three colors = (10/20) + (8/20) + (2/20)

= 1 = 100%

Answer 2

10 black- 10/20 - 50%

8 red- 8/20 - 40%

2 white - 2/20 -10%
