Returns the probability that a random variable from a normally distributed data set is less than or equal to a specified value, or exactly equal to a specified value.

NORMDIST(x,mean,standard_deviation,cumulative)

`x`Numeric. The value for which you want to calculate the probability.

`mean`Numeric. The mean value of the data set.

`standard_deviation`Numeric. The standard deviation of the data set. The

`standard_deviation`value must be greater than 0.`cumulative`Logical. Specify T to calculate the probability that a random variable is less than or equal to

`x`(cumulative probability), or F to calculate the probability that a random variable is exactly equal to`x`(simple probability).

Numeric.
