Consider the experiment of flipping a fair coin until we get two heads (not necessarily consecutive). Let X be the total number of flips we had to make. Let Y be the number of tails we got. Find E[X∣Y=y] where y=9.

Step 1
To find \( E[X \mid Y = 9] \), where \( X \) is the total number of flips until we get two heads and \( Y \) is the number of tails, we can follow these steps: Show more…

Rework the original problem below using conditional expectation: Compute E(Y|X=k) for k=0, 1, 2, and argue by looking at the PMF (Probability Mass Function) thus found, that the random variable E(Y|X) equals X/2. Find then E(Y) as E(E(Y|X)). Original Problem: Let X be the number of heads in two tosses of a fair coin (that is, X is Bin(2, 1/2)). Now toss a second fair coin as many times as the number of heads you got with the first coin, and let Y be the number of heads obtained with the second coin. Obtain the table of the joint probabilities, the marginal probabilities, and the expected values E(X) and E(Y).

We consider n independent tosses of a biased coin whose probability of heads, Y, is uniformly distributed over the interval [0.1, 0.8]. Let X be the number of heads obtained. (1) (5 points) Let α and β be real numbers such that E[X|Y] = α · Y + β. Derive the values of (α, β). (2) (4 points) Derive E[X] and var(Y). (3) (6 points) Calculate the value of var(X).
