Coin 1 comes up heads with probability 0.6 and coin 2 with probability 0.5. A coin is continually ﬂipped until it comes up tails, at which time that coin is put aside and we start ﬂipping the other one. (a) What proportion of ﬂips use coin 1? (b) If we start the process with coin 1 what is the probability that coin 2 is used on the ﬁfth ﬂip? (c) What proportion of ﬂips land heads?
