NORM.S.DIST
Category: Statistical Function.
Description: Returns the standard normal distribution (having a mean of zero and a standard deviation of one).
Syntax: NORM.S.DIST(z,cumulative)
'Z' is the value at which you wish to evaluate the distribution function.
'Cumulative' is the logical value that determines the form of the function.
If 'cumulative' is TRUE, NORMS.DIST returns the cumulative distribution function; otherwise, it returns the probability mass function.
