I toss 3 fair coins, and then re-toss all the ones that come up tails. Let X denote the number of coins that come up heads on the first toss, and let Y denote the number of re-tossed coins that come up heads on the second toss. (Hence 0 ≤ X ≤ 3 and 0 ≤ Y ≤ 3 − X.) (a) Determine the joint pmf of X and Y , and use it to calculate E(X + Y )....

Q3. Suppose you toss n “fair” coins (i.e., heads probability = 1/21/2). For every coin that came up tails, suppose you toss it one more time. Let X be the random variable denoting the number of heads in the end. What is the range of the variable X (give exact upper and lower bounds) What is the distribution of X? (Write down the name and give a convincing explanation.)
