A bag contains 5 red , 7 green and 4 white balls, three balls are drawn one after the other without replacement. Find the probability that the balls drawn are white, green and green respectively.

Dear student

probability of first ball to be white = 416after this white ball is picked, we have 15 balls of which 7 is greenprobability of green = 715after this green ball is picked, we have 14 balls of which 6 is greenprobability of green = 614required probability =  416×715×614=120

This problem is based on combination since it is without replacement
4/16 + 7/16*6/15
