WebbWe are given that a coin has probability of heads equal to p and tails equal to q and it is tossed successively and independently until a head comes twice in a row or a tail comes twice in a row. What isthe expected value of the number of tosses? Solution: Let X be a random value that tracks the number of tosses. WebbThat is because Heads and Tails are equally likely. The probabilities of each event - Heads and Tails - are both equal. Because they are equal, they are both given a probability of ½. So: Probability of Heads = ½ and Probability of Tails = …
