WebThere are two types of random variables, discrete random variables and continuous random variables. The values of a discrete random variable are countable, which means the values are obtained by counting. All random variables we discussed in previous examples are discrete random variables. WebJoint Distributions Suppose X and Y are two random variables defined on the same outcome space. We will use the notation P ( X = x, Y = y) for the probability that X has the value x and Y has the value y. That is, P ( X = x, Y = y) = P ( { X = x } ∩ { Y = y })
