I toss a coin which lands heads with probability p. Let WH be the number of tosses tillI get a head, WHh the number of tosses till I get two heads in a row, and WHHH thenumber of tosses till I get three heads in a row. Find:a) E(WH); b) E(WHH) (Hint: condition on whether the first toss was heads ortails); c) E(WHHH) [Hint: condition on WT).d) Generalize to find the expected number of tosses to obtain m heads in a row.

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
