If two balls are drawn from a bag containing 3 white, 4 black and 5 red balls, then the probability that the drawn balls are of different colours is

A bag contains 6 white and 4 black balls. Two ball are drawn at random. The probability that they are of the different colour is

A bag contains 5 white, 4 black and 6 red balls. A ball is drawn at random. The probability that the balls drawn is not white is:

A bag contains 2 red, 3 black , 4 white balls. 2 balls are drawn at random . The probability that they are different colours is

A bag contains 3 red, 4 white and 6 blue balls. 3 balls are drawn at random. The probability that they are of different colours is

A bag contains 3 red,4 white and 5 blue balls. If two balls are drawn at random. The probability that they are of different colours is……….

from a bag containing 4 red and 2 black balls, two balls are drawn. the probability of getting two black balls is:

A bag contains 5 red and 4 green balls and another bag contains 3 red and 7 black balls. If a ball is drawn from each bag. Find the probability that both are of different colours.

A bag contains 4 red and 5 black balls, a second bag contain 3 red and 7 black balls. One ball is drawn at random from each bag, find the probability that the balls are of different colour.
