NORMSDIST(x)

Returns the probability of getting less than or equal to a particular value in a normal distribution (no cumulative).

xThe number from the distribution.

Remarks

* NORM.S.DIST was added in Excel 2010 to replace this function.
* Returns the probability given a z-value.
* The standard normal distribution is a continuous distribution.
* If "x" is not numeric, then #VALUE! is returned.
* mean 0, standard deviation 1
* In Excel 2010 the accuracy of this function was improved.
* For the Microsoft documentation refer to support.office.com

2 - If you are one standard deviation above the mean, then you have a percentile rank of 84%.
4 - no skewwness, symmetrical around 0.
