WebThis calculus 2 video tutorial provides a basic introduction into probability density functions. It explains how to find the probability that a continuous random variable such as x in … WebThe cumulative distribution function (" c.d.f.") of a continuous random variable X is defined as: F ( x) = ∫ − ∞ x f ( t) d t. for − ∞ < x < ∞. You might recall, for discrete random variables, that F ( x) is, in general, a non-decreasing step function. For continuous random variables, F ( x) is a non-decreasing continuous function. chips mother crossword
