NORM.DIST

NORM.DIST(x, mean, standard_dev, cumulative)

Returns the probability distribution function OR the cumulative probability function for a normal distribution.

x	The number from the distribution.
mean	The arithmetic mean of the distribution.
standard_dev	The standard deviation of the distribution.
cumulative	A logical value indicating the type of function to use: False (or 0) = individual probability (equal to) True (<> 0) = cumulative probability (equal to or less than)

REMARKS

* For an illustrated example refer to the page under Distributions
* The normal distribution is a continuous distribution
* If "cumulative" = False, then the height of the curve at "x" is returned.
* If "cumulative" = True, then the area under the curve to the left of "x" is returned.
* You can use the NORM.S.DIST function to return the probability distribution function for a standard normal distribution.
* You can use the NORM.S.INV function to return the inverse of the probability distribution function for a standard normal distribution.
* You can use the NORM.INV function to return the probability distribution function for a standard normal distribution.
* This function was added in Excel 2010 to replace the NORMDIST function.
