Expert Solution
Introduction

The probability distribution gives likelihood of each outcome in a random experiment.

It gives the possibility of each outcome.

In probability distribution table X is random variable and P(X) is the probability of occurrence.

X X1 X2 X3 Xn sum
P(X) P1 P2 P3 Pn 1

 In above table probability should always greater than 0 and sum of probabilities is always 1
