PROBABILITY DISTRIBUTION
If X is discrete random variable which takes the values of x1, x2,x3….. Xn and the corresponding probabilities are p1, p2, ……….pn, then, X follows the probability distribution. The two main properties of probability distribution are: (i) P(Xi) is always greater than or equal to zero and less than or equal to one, and (ii) the summation of probability distribution is always equal to one. For example, tossing of an unbiased coin twice.
Then the
probability distribution is:
Let X be the discrete random variable which takes the value of x1, x2,…… xn then the respective probability is p1, p2, ………… pn, then the
