Properties of a probability mass function. A function is a probability mass function if: 2012-11-06 · 3.1 Joint probability mass and density functions Recall that a basic probability distribution is defined over a random variable, and a random variable maps from the sample space to the real numbers.What about when you are interested Marginal probability mass function Given a known joint distribution of two discrete random variables, say, X and Y, the marginal distribution of either variable – X for example — is the probability distribution of X when the values of Y are not taken into consideration. Suppose the joint probability density function of (X, Y) is 0 otherwise 0 1, C x y2 y x f x y a) Find the value of C that would make f x, a valid probability density function.
