Definitions:

Probability

The measure of the likelihood that an event will occur, represented as a number between 0 and 1.

Exponentially Distributed

Pertains to a type of statistical distribution that describes the time between events in a process where events occur continuously and independently at a constant average rate.

Variance

Variance is a statistical measure that represents the dispersion or spread of a dataset by calculating the average of the squared differences from the mean, indicating how much the data points in a set differ from the mean value.

Exponential Distribution
