Let f(x) and F(x) denote, respectively, the pdf and CDF of the continuous random variable X. Let x0 X be fixed. The conditional pdf of X given X > x0 is defined by f(x|X>x0)=f(x)/1-F(x0),x x0) is a pdf. Let f(x) = e^-x, 0 1). (This is called the memoryless property of the exponential distribution; see also textbook exercise 6.16)
