Webb7 dec. 2024 · Example 2. What is the joint probability of getting a head followed by a tail in a coin toss? Event “A” = The probability of getting a head in the first coin toss is 1/2 = 0.5. Event “B” = The probability of getting a tail in the second coin toss is 1/2 = 0.5. Therefore, the joint probability of event “A” and “B” is P (1/2) x P ...

You take all possible pairs ( x, y), and for each pair, you multiply their product x y by the probability p X, Y ( x, y) of this pair occuring, and then sum up the results. This also answers what the meaning of p X, Y ( x, y) is: It is the joint probability of obtaining the values X = x and Y = y, so for instance, p X, Y ( 1, 3) = 0. ...
