Webwe see that the cumulative distribution function F ( x) must be defined over four intervals — for x ≤ − 1, when − 1 < x ≤ 0, for 0 < x < 1, and for x ≥ 1. The definition of F ( x) for x ≤ − 1 is easy. Since no probability accumulates over that interval, F ( x) = 0 for x ≤ − 1. Similarly, the definition of F ( x) for x ≥ 1 is easy.
