See less## An urn contains 9 red, 7 white, and 4 black balls. A ball is drawn at random. Find the probability that the ball is drawn is not white

Total number of Red balls = 9 Total number of white balls = 7 Total number of black balls = 4 Total number of balls = 9 + 7 + 4 = 20 We know, Probability of occurrence of an event = (Total number of favorable outcomes) / (Total number of outcomes) Â P(getting not white ball) = 1 â€“ P(getting a white bRead more

Total number of Red balls = 9

Total number of white balls = 7

Total number of black balls = 4

Total number of balls = 9 + 7 + 4 = 20

We know, Probability of occurrence of an event = (Total number of favorable outcomes) / (Total number of outcomes)

Â P(getting not white ball) = 1 â€“ P(getting a white ball) = 1 â€“ 7/20 = 13/20
