Gamma distribution

The gamma distribution is like a bell-shaped curve, but spread out more. It's often used to describe something that can be measured, like how long it takes to do something or how much of something there is. The shape of the curve tells you how likely it is that something will happen. For example, if you measure how long it takes kids to do their homework, the gamma distribution will show you the probability that a certain number of kids will finish in a certain amount of time.
