Discover what a uniform distribution is, its types, and examples like dice and cards, where each outcome is equally likely, ensuring a balanced probability.

If we plot the probability (density) function (PDF) on a graph with vertical axis as probability and horizontal axis as value of X, then that plot is called a "distribution." The PDF is aptly named ...
