          Consider two random variables X and Y with joint probability mass function as follows

        Y = 2  Y = 4  Y = 5
X = 1   1/12   1/24   1/24
X = 2   1/6    1/12   1/8
X = 3   1/4    1/8    1/12

Find P(X <= 2, Y <= 4)
Find marginal PMF of X and Y
Are X and Y independent?

Step 1

| | Y=2 | Y=4 | Y=5 | |---|-----|-----|-----| | X=1 | 1 | 3 | 0 | | X=2 | 6 | 8 | 0 | | X=3 | 0 | 4 | 0 | Now, we can find the probability P(X < 2, Y < 4) by summing the probabilities in the table where X < 2 and Y < 4. P(X < 2, Y < 4) = Show more…
