A continuous random variable takes on an uncountably infinite number of possible values. For a discrete random variable X that takes on a finite or countably infinite number of possible values, we determined P ( X = x) for all of the possible values of X, and called it the probability mass function ("p.m.f.").

Let X = (X1,X2) denote a discrete bivariate rv with joint pmf pX(x1,x2) and marginal pmfs p X1(x1) and p X2(x2). For any x1 such that p X1(x1) > 0, the conditional pmf of X2 given that X1 = x1 is the function of x2 defined … espn 710 mason and ireland

NettetDefinition of a Joint Probability Density Function. A bivariate function with values f(x 1, x 2) defined over the x 1x 2-plane is called a joint probability density function of the continuous random variables X 1 and X 2 if, and only if, P [(X 1, X 2) ∈ A] = Z A Z f(x 1, x 2)dx 1 dx 2 for any region A ∈ the x 1x 2-plane (3) 4.2.
