The two functions are also related mathematically — you can obtain the cumulative distribution function of a random variable by integrating its probability density function. However, there are ...

A probability density function (PDF) ... A cumulative distribution function (CDF) instead depicts how these marginal probabilities add up, ultimately reaching 100% (or 1.0) ...

Probability distributions are characterized as either discrete or continuous, and as working as either a probability density function, or a cumulative distribution. Discrete vs. Continuous ...

Cumulative probability distribution. A function that shows the probability that the random variable will attain a value less than or equal to each value that the random variable can take on.
