The cumulative distribution function (CDF) gives the probability that a random variable $X$ is less than or equal to a specific value $x$. It is defined as:

$$F(x)=P(X\le x)$$

For a discrete variable, the CDF is the sum of probabilities for all outcomes up to $x$. For a continuous variable, it is the integral of the probability density function (PDF) up to $x$. The CDF always ranges from 0 to 1 and is non-decreasing. Sablon:Engl
