Finаlly, sоme questiоns аbоut а probabilistic problem. Given a sequence of coin flips, we define a singleton as an H with no H immediately before or after, or a T with no T immediately before or after. For example, the sequence T T H T T T H H H H T T H T H H T has 4 singletons (boldfaced). Assume that we toss a fair coin n times (n >= 2). With X a random variable denoting the number of singletons in the resulting sequence, we want to calculate E[X]. For that purpose, for each i in 1..n we define an indicator random variable X_i for the event that toss i is a singleton; thusX = sum_{i=1}^n X_i.Observe that when n = 2 we have E[X] = (2+2+0+0)/4 =1 since each of the sequences HT and TH has 2 singletons, while each of the sequences HH and TT have 0 singletons.
