If the coin is fair, the probability is 1/4.

The probability of flipping 91 coins and getting a head 91 times in a row is 1/291 or (1/2)91 or 4.039E-28. The (1/2)91 is when there is exactly 91 coin tosses or n = 91. As the number of trials increases so does the probability of at least 1 run of length 91. The average number of coin flips to see 91 in a row is 4.951760157141521e+27
