1.) Let \( \Omega \) be a deck of cards. Define a random variable \( X \) such that for any card \( c \) in the deck\[X(c) = \begin{cases} \text{the number value on the card for all numbered cards} \\10 \text{ for any face cards (jack, queen, king)} \\11 \text{ for any ace}\end{cases}\]What is \( \mathbb{E}[X] \)?

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

8 For this problem, assume there are 3 grey females, 4 grey males, 2 white females, and 3 white males. As in the book, the biologist selects two mice randomly. (1) What is the probability of selecting two males given that both are grey? (2) What is the probability of selecting 1 mouse of each gender given that both are grey?
Cards are picked sequentially without replacement from a well-shuffled deck of 52 cards until either all SPADES are found or all CLUBS are found. Let X denote the number of cards picked. Find E(X) using indicator random variables.
Count the number of ways to get 12 by the 5-dice, i.e., to represent 12 = x₁ + x₂ + x3 + X4 + X5, where 1 ≤ x ≤ 6 (1+2+3+4+3 is different from 2+1+3+3+4).
3. An integer is randomly chosen from the set 1, 2,..., 100. If this integer is divisible by 2 we let Y = 0, and if it is not divisible by 2 but is divisible by 3 then Y = 1. We let Y = 2 in all other cases. Find mean and variance of Y.
