(Competing patterns among coin flips) Suppose that Xn,n 2 1 are i.i.d. random variables with P(X1 = 1) = P(X1 = 0) = }. (These are just i.i.d. fair coin flips.) Let A = (a1, a2, a3) = (0,1, 1), B = (b, b2, b3) = (0,0, 1). Let TA = min(n 2 3: {X-2, Xn-1, Xn) = A} be the first time we see the sequence A appear among the X, random variables, and define Tg similarly for B. Find the probability that P(TA

3. (Competing patterns among coin flips) Suppose that Xn, n 2 1 are i.i.d. random variables with P(X1 = 1) = P(X1 = 0) = }. (These are just i.i.d. fair coin flips.) Let A = (a1, a2, a3) = (0,1, 1), B = (b1, b2, b3) = (0,0, 1). Let TA = min(n 2 3: {X,-2, Xn-1, Xn) = A} be the first time we see the sequence A appear among the X, random variables, and define Tg similarly for B. Find the probability that P(TA < TB). (This is the probability that THH shows up before TTH in a sequence of fair coin flips.)
