Madelyn Goodnight / Investopedia A probability distribution is a statistical function that describes all values a random variable can take within a given range and the likelihood that they will.

A normal distribution, for instance, is depicted by a bell-shaped curve with an uninterrupted line covering all values across its probability function. A discrete probability model is a ...
