Suppose that you have 7 green cards and 5 yellow cards. The cards are well shuffled. You randomly draw two cards with replacement. Round your answers to four decimal places. G1 = the first card drawn is greenG2 = the second card drawn is green a. P(G1 and G2) = b. P(At least 1 green) = c. P(G2|G1) =
The zebra plays a game in which in every turn she randomly chooses a letter from the set {A,B,C}, independently of other turns, and registers the outcome in a list. 1. Assume that the zebra plays exactly 4 turns, and let X denote the number of distinct outcomes she registers. 2. The first moment of X is 3. The probability that both A and B are registered at some point during the 4 turns she plays is 4. The second moment of X is 2. Now assume that the zebra plays until she registers every possible outcome at least once, that is, once she has registered at least one of each of the outcomes she stops. The expected number of turns she plays is

Roll a pair of fair six-sided dice and let X be 1 if the dice land showing the same number of spots, and 0 otherwise. For example, if both dice land 2, then X = 1, but if one lands 2 and the other lands 3, then X = 0. What is P(X = 1)? Explain your reasoning below.
