In this correspondence, we give a sufficient condition for the exponential decay of the tail probability of a nonnegative random variable. We consider the Laplace-Stieltjes transform of the ...

Let's work through a brief example calculating the probability mass function for a discrete random variable! A probability is a number in the range [0,1] that is calculated as the frequency expressed ...

Example 3: A fair coin is tossed 3 times. Random variable S is the total number of heads in the three tosses. Given a random variable, X, and real number, x, p (x) = P [X=x] is the probability that X ...

Notice that the sum of all probabilities in this table is 1. Since f (x,y) is a probability distribution, it must sum to 1. Adding probabilities across the rows you get the probability distribution of ...
