EXPON.DIST

EXPON.DIST(x, lambda, cumulative)

Returns the probability distribution function OR the cumulative probability function for an exponential distribution.

x	The value of the function.
lambda	The parameter value.
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 exponential distribution is a continuous distribution
* If "x" < 0, then #NUM! is returned.
* If "x" is not numeric, then #VALUE! is returned.
* If "lambda" = 0, then #NUM! is returned.
* If "lambda" is not numeric, then #VALUE! is returned.
* If "cumulative" = False or 0, then the height of the curve at "x" is returned.
* If "cumulative" = True or 1, then the area under the curve to the left of "x" is returned.
* This function was added in Excel 2010 to replace the EXPONDIST function.
