Let T_c be the first-passage time to the origin for a standard Brownian motion starting from c > 0. We define S - l/T_c.

(a) Calculate the probability density function of S. What is the distribution of the random variable S?

(b) Find a number b (in terms of the constant c) for which we have P[S ≤ b] = 0.5.
