A bag contains 6 red, 4 white and 8 blue balls. If three balls are drawn at random, find the probability that one is red, one is white and one is blue

given: 6 red, 4 white and 8 blue balls

formula:


three balls are drawn so, we have to find the probability that one is red, one is white and one is blue


total number of outcomes for drawing 3 balls are 18C3


Therefore n(S)= 18C3=816


Let E be the event that one red, one white and one blue ball is drawn


n(E)= 6C14C18C1=192
