In other words, U is a uniform random variable on [0;1]. Most random number generators simulate independent copies of this random variable. Consequently, we can simulate independent random variables having distribution function F X by simulating U, a uniform random variable on [0;1], and then taking X= F 1 X (U): Example 7.
