Find a constant C such that p is a probability density function on the given interval and compute the probability indicated.
p(x)=(Ce^(-x))/(1+e^(-2x)) on (-infty ,infty )
(For a constant C, express numbers in exact form. Use symbolic notation and fractions where needed. For a probability, use decimal notation. Give your answer to four decimal places.)
