What are the two key properties of a discrete probability distribution? 0 ≤ P (X = x) ≤ 1 and ∑P (X=xi) = 1. All of the following are features of a discrete uniform distribution EXCEPT. The distribution is bell-shaped. WebTo 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 ...
