probability distribution
Chance spread mathematically
A probability distribution is a mathematical function that describes how likely different outcomes are in a random process or experiment.
In statistics and probability theory, it assigns probabilities to all possible values a variable can take, with the total always summing to one.
Distributions come in many forms—the bell-shaped normal distribution, the coin-flip binomial, the waiting-time exponential—each suited to modeling different kinds of uncertainty.
The data follows a normal probability distribution.
