Question

A bag contains 8 red, 2 black and 5 white balls. One ball is drawn at random. What is the probability that the ball drawn is not black?

Options

• `8/15`

• `2/15`

• `13/15`

• `1/3`

Answer 1

`bb(13/15)`

Explanation:

Total possible outcomes = Total number of balls

= (8 + 2 + 5)

= 15

Total number of non-black balls = (8 + 5) = 13

∴ P(getting a ball that is not black) = `13/15`.
