A bag contains 3 red and 4 black balls. One ball is drawn and then replaced in the bag and the process is repeated. Every time the ball drawn is red we say that the draw has resulted in success. Let X be the number of successes in 3 draws. Assuming that at each draw each ball is equally likely to be selected, find the probability distribution of X.

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.
