Problem 5 Two fair dice are tossed, and ((X,Y) denote the number of spots on the first and on the second dice. Consider two random variables: U = X + Y and W - X - Y . (A) Derive the distribution of U. List all possible values and evaluate their probabilities. (B) Derive the distribution of W. List all possible values and evaluate their probabilities. (C) Determine the conditional probability P (6 SU <71W <1]

Two fair 6-sided dice are tossed. Let X denote the number appearing on the first die and let y denote the number appearing on the second die. Show that X, Y are independent by showing that P(X = x, Y = y) = P(X = x) x P(Y = y) for all (x,y) pairs.

A pair of balanced dice is tossed. If X equals the total number of spots showing on the dice, then, for k = 2, 3,...,12, find: a. Pr(4≤X≤9) b. Pr(4<X≤9) c. Pr(4≤X<9) d. Pr(4<X<9)

Shandelle rolls a pair of fair dice and sums the number of spots that appear on the up faces. She then flips a fair coin the number times associated with the sum of the spots. For example, if she rolled a 3 and a 4, then she flips the fair coin 7 times. If the coin flipping part of the random experiment yielded an equal number of heads and tails, find the probability that she rolled an 8 on the...

In a particular game, a fair die is tossed. If the number of spots showing is a six, you win $6, if the number of spots showing is a five, you win $3, if the number of spots showing is 4, you win $2, and if the number of spots showing is 3, you win $1. If the number of spots showing is 1 or 2, you win nothing. You are going to play the game twice. Let X be...

A fair coin is tossed 3 times. Let X denote a 0 if the first toss is a head or 1 if the first toss is a zero. Y denotes the number of heads. Find the distribution of X. Of Y. And find the joint distribution of X and Y.
