A coin is rigged so that the probability of tossing a head is 0.41. The coin is tossed until the first time that a head turns up. Let T record the number of tosses/trials up to and including the first head. What is the probability distribution of T? Your answer should be a function of k. What is the probability that there are no heads in the first 3 tosses? P(T > 3) What is the probability that the first head is on the 8th toss? P(T = 8) = What is the probability that the first head is on the 8th toss given that there are no heads in the first 3 tosses? P(T = 8|T > 3) =
