1. A coin is tossed 3 times. Let X be the number of heads obtained. X can take values {0, 1, 2, 3}. Find the probability distribution of X.
A bag contains 3 red balls and 2 blue balls. One ball is drawn at random. Let X = 1 if a red ball is drawn, and X = 0 if a blue ball is drawn. Write the probability distribution of X.
