2. (20 marks) Toss a coin at time points t = 1, 2, .... Denote the outcome of each toss head-facing-up and tail-facing-up by a 0 and a 1, respectively. Let A = (011) and N be the waiting time for A (number of tosses required to see the first occurrence of the pattern). Find the mean waiting time E[N] while assuming that in each toss the head-facing-up outcome occurs with probability 3/4.
