WebbTo calculate probabilities for an exponential probability density function, we need to use the cumulative density function. As shown below, the curve for the cumulative density function is: f(x) = 0.25e –0.25x where x is at least zero and m = 0.25. For example, f(5) = 0.25e (-0.25)(5) = 0.072. In other words, the function has a value of .072 ...
