CDF

CDF[dist, x]
gives the cumulative distribution function for the symbolic distribution dist evaluated at x.

CDF[dist]
gives the CDF as a pure function.

CDF[dist, x] gives the probability that an observed value will be less than or equal to x.

For continuous distributions, CDF[dist, x] is the integral of the probability density function from the lowest value in the domain to x.

For discrete distributions, CDF[dist, x] is the sum of the probability density function from the lowest value in the domain to x.
