Question

Matlab program to calculate joint probability density function

Answer 1

Joint probability is the probability of two events happening together. The two events are usually designated event A and event B. In probability terminology, it can be written as:

p(A and B)
or
p(A ∩ B)
Joint probability is also called the intersection of two (or more) events. The intersection can be represented by a Venn diagram:



A Venn diagram intersection shows the intersection of events A and B happening together.


Example: The probability that a card is a five and black = p(five and black) = 2/52 = 1/26. (There are two black fives in a deck of 52 cards, the five of spades and the five of clubs).

You can find several more examples here: Probability of A and B.
