NORM.S.DIST(x, cumulative)

Returns the probability of getting less than or equal to a particular value in a standard normal distribution.

xThe number from the distribution.
cumulativeThe type of function to use:
True = cumulative probability function (less than)
False = probability density function (equal to)

Remarks

* Added in Excel 2010.
* This function replaces the NORMSDIST function.
* The standard normal distribution is a continuous distribution.
* If "x" is not numeric, then #VALUE! is returned.
* If "cumulative" = True, then the area under the curve to the left of "x" is returned. This uses the cumulative distribution function.
* If "cumulative" = False, then the height of the curve at "x" is returned. This uses the probability density function.
* mean 0, standard deviation 1
