A biased coin, with a 40% chance that a tail will come up, is tossed twice. Let A denote the number of tails on the first toss and B the total number of tails on the 2 tosses. Find A. the joint probability distribution of A and B; B. the marginal distribution of A C. the probability (B≥1) D. the conditional distribution of B given A=1 E. The probability (B≤1/A=1)
