The probability of obtaining a head in one toss of a coin is 1/2 and the probability of obtaining two heads in two coin tosses is 1/4. It follows that the probability of obtaining five heads in five coin tosses is 1/32. Suppose I flip a coin four times and obtain four heads. Then it is better to bet on tails for the fifth flip because the probability of five heads in a row is very small.
