उत्तर
GIVEN: A bag contains5 red, 8 green and 7 white balls
TO FIND: Probability of getting a white ball or a green ball.
Total number of balls `5+8+7=20`
Total number of green or white balls `8+7=15`
`"We know that PROBABILITY" =" Number of favourablr event"/"Total number of event"`
`"Hence probability of getting a green or a white ball "= 15/20=3/4`
`"Hence probability of getting an green or white ball "= 3/4`
