Explain the terms probability Mass function

योग

उत्तर

 If X is a discrete random variable with distinct values x1, x2, …. xn, …, then the function, denoted by Px(x) and defined by

`"P"_"X"(x) = "p"(x) = {("P"("X"=x_i),= "P"_i = "P"(x_i),if,x=x_i",",i=1","2","....","n","...),(0 ,"",if,x!=x_i,):}`

This is defined to be the probability mass function or discrete probability function of X.
