Question

Two men A and B toss a coin in turn until a head occurs. The man who tosses a head wins. a) Find the probability that A wins. b) If the coin is biased and head occurs with probability p, what is the probability that B wins? c) Let X be the number of trials required to produce the 1st success, say a head, in a toss of a fair coin. Find the expected number of trials required to produce the success if the probability of a success in a particular trial is p.

Step 1

Since A wins if he tosses a head on the first try or if B tosses tails and A tosses a head on the second try, the probability that A wins can be calculated as follows: P(A wins) = P(A tosses head on 1st try) + P(B tosses tails and A tosses head on 2nd try) P(A Show more…
