A dresser contains 4 yellow socks and 5 blue socks. Draw three socks with replacement. Let X be the number of yellow socks on the first two draws, and Y the number of yellow socks on the last two draws. Make a table showing the joint distribution of X and Y . Compute the expected number of yellow socks on the first two draws.

A box is filled with 15 different socks: 10 green and 5 yellow. Three socks are picked from the box (leaving 12 in the box). Let x be the random variable describing the number of green socks that are selected. Let events A and B be described as follows: A = the event that not all three socks are green. B = the event where the first sock selected is green. Find P(A), P(B), and P(A & B). Show any...

A box contains 3 blue and 4 yellow marbles. Marbles are drawn out one at a time,the drawn marbles not being replaced. Let X = number of drawings made until all the marbles remaining in the box are of the same color. Construct the probability distribution of X. That is, a table with the possible values of X and their corresponding probabilities.
