One Dimensional Distributions - College of Computing The Exponential RV The exponential RV with parameter >0 has the pdf f X(x) = e xfor x>0 and 0 otherwise. The cdf is F X(x) = P(X x) = Z x 0 e x= e x x 0 = 1 e x for x>0 and 0 otherwise. Note that the pdf decreases exponentially fast as xgrows (for positiv
Probability mass function - Wikipedia, the free encyclopedia In probability theory and statistics, a probability mass function (pmf) is a function that gives the probability that a discrete random variable is exactly equal to some value.[1] The probability mass function is often the primary means of defining a disc

Section 3.4: The Binomial Probability Distribution †Let X be the total number of successes among the n trials of a binomial experiment. † Then, we call X follows a binomial distribution, and we write X » Bin(n;p); where p is the probability of success and 1 ¡ p is the probability of failure † The PMF of X
