Probability density function mean
Webb15.5 Mean and Variance of the Binomial. Many of the well-known probability distributions, including the binomial distributions, have what I like to call ‘short-cut’ formulas for finding the expected value and variance that is easier than the formulas seen previously for ‘generic’ discrete probability distributions. 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 ...
