### NORM.S.DIST(x, cumulative)

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

 x The number from the distribution. cumulative The 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* For the Microsoft documentation refer to support.microsoft.com
