See lessAn 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)  P(getting not white ball) = 1 – 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)
 P(getting not white ball) = 1 – P(getting a white ball) = 1 – 7/20 = 13/20
