let x and y be the random variables that count the number of heads and the number of tails that come up when two fair coins are flipped. Show that X and Y are not independent.

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 )....

Let X denote the number of heads than occur when four coins are tossed at random. Under the assumptions that the four coins are independent and the probability of heads on each coin is 1/2,X is B(4,1/2). One hundred repetitions of this experiment results in 0,1,2,3, and 4 heads being observed on 7,18,40,31, and 4 trials, respectively. Do these results support the assumption that the distribution of X is B(4,1/2)?
