SOLUTION: A symmetric coin is tossed n times, the outcomes are denoted by letters H, S. With a letter of length n, the sequence is shortened by crossing out all letters H before the first S

Question 1200588: A symmetric coin is tossed n times, the outcomes are denoted by letters H, S. With a letter of length n, the sequence is shortened by crossing out all letters H before the first S and all H after the last S (if any). What is the probability that the resulting truncated sequence will contain no more than the letter m? ([n, m] = [14, 4])
