How do you find the norm of CDF?

The CDF function of a Normal is calculated by translating the random variable to the Standard Normal, and then looking up a value from the precalculated “Phi” function (Φ), which is the cumulative density function of the standard normal. The Standard Normal, often written Z, is a Normal with mean 0 and variance 1.
