Question: Show that an exponentially distributed random variable X with probability density function has expected value E(X) = 1/k. f(x) = = [ke-kx lo if x

Show that an exponentially distributed random variable X with probability density function


f(x) = = [ke-kx lo if x 0 if x < 0


has expected value E(X) = 1/k.

f(x) = = [ke-kx lo if x 0 if x < 0
