pages.cs.wisc.eduJoint Probabilities For two events, E and F, the joint probability, written P(EF), is the the probability that both events occur. For example, let E be “the probability that a die roll is even” and F be “the probability that a die roll is greater than 3”. We have the following sets to describe each event: E = {2, 4, 6} F = {4, 5, 6}
Reading 7a: Joint Distributions, Independence
ocw.mit.edu18.05 class 7, Joint Distributions, Independence, Spring 2014 3. 3.2 Continuous case. The continuous case is essentially the same as the discrete case: we just replace discrete sets of values by continuous intervals, the joint probability mass function by a joint probability density function, and the sums by integrals.
