Uniform Distribution
In a uniform distribution, each outcome (1, 2, or 3) has an equal probability of occurring (1/3 or 33.33%). This type of distribution is often used in fair games of chance, such as rolling a die.
-
Non-Uniform Distribution
In a non-uniform distribution, the outcomes do not have an equal probability of occurring. For example, a biased coin may have a higher probability of landing on heads than tails.
