Nettet14.1 - Probability Density Functions. 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."). NettetThe first two conditions in Definition 5.2.1 provide the requirements for a function to be a valid joint pdf. The third condition indicates how to use a joint pdf to calculate probabilities. As an example of applying the third condition in Definition 5.2.1, the …

NettetThis is the normalization condition for joint probability density functions. Intuitively, the joint probability density function just gives the probability of finding a certain point in two-dimensional space, whereas the usual probability density function gives the probability of finding a certain point in one-dimensional space.
