A bag contains 2 white and 1 red ball. One ball is drawn at random and then put back in the bag after noting its colour. The process is repeated again. If 'X' denotes the number of red balls recorded in the two draws, describe 'X'.

A bag contains 4 white and 3 black balls. Two balls are drawn at random. Find the probability that they are of the same colour.

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:

Bag A contains 6 red and 4 black balls . One ball is drawn at random from the bag. Find the probability that it was a red ball.

A bag contains 8 red, 3 white and 9 blue balls. Three balls are drawn at random from the bag. Determine the probability that none of the balls is white .

A bag contains 5 black and 3 white balls. Two balls are drawn at random. Find the probability of drawing two white balls.

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.

A bag contains 3 red balls and 5 black balls. A ball is drawn at random from the bag. What is the probability that is the ball drawn is : red?

A bag contains 2 red and 3 black balls. One ball is drawn and then put back in the bag. The process is repeated three times. Every time the ball drawn happens to be red we say that the saw has resulted in a success. Let X denote the number of success recorded in 3 draws. show that X can be considered as random variable and exhibit it as a function one the sample space of the experiment.

A bag contains 5 red and 3 blue balls. If 3 balls are drawn at random without replacement, the probability of getting exactly one red balls
