Chapter 7, Problem 7.11(choose chapter or problem)
Consider n independent flips of a coin havingprobability p of landing on heads. Say that achangeover occurs whenever an outcome differsfrom the one preceding it. For instance, if n =5 and the outcome is HHTHT, then there are3 changeovers. Find the expected number ofchangeovers.Hint: Express the number of changeovers as thesum of n 1 Bernoulli random variables.
