The Cumulative Distribution Function: Interpretation and determination of Probabilities

A cumulative distribution offers a convenient tool for determining probabilities for a given random variable. As you will recall from a previous learning outcome statement, a cumulative distribution function, F(x), gives the probability that the random variable X is less…

Calculating Probabilities given the Discrete Uniform and the Binomial Distribution Functions.
