Probability mass function plays an important role in statistics. It defines the probabilities for the given discrete random variable. It integrates the variable for the given random number which is equal to the probability for the random variable. It is used to calculate the mean and variance of the discrete distribution.

4.2 Discrete random variables: Probability mass functions. Discrete random variables take at most countably many possible values (e.g.

Suppose one has a box of ten balls – four are white, three are red, and three are black. The phrase distribution function is usually reserved exclusively for the cumulative distribution function CDF (as defined later in the book). The word distribution, on the other hand, in this book is used in a broader sense and could refer to PMF, probability density function (PDF), or CDF. Moments of a Probability Mass function. The n-th moment about the origin of a random variable is the expected value of its n-th power.
