Counting joint distribution
WebThe intersection of events A and B, written as P (A ∩ B) or P (A AND B) is the joint probability of at least two events, shown below in a Venn diagram. In the case where A and B are mutually exclusive events, P (A ∩ B) = 0. … 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 })

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.

WebIn the discrete case, we can obtain the joint cumulative distribution function (joint cdf) of X and Y by summing the joint pmf: F(x, y) = P(X ≤ x and Y ≤ y) = ∑ xi ≤ x ∑ yj ≤ yp(xi, yj), where xi denotes possible values of X and yj denotes possible values of Y.
