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

  • `18/15`

  • `2/15`

  • `13/15`

  • `1/3`

MCQ

Solution

`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`
