Excel EXPON.DIST Function

Description

The Excel EXPON.DIST function returns the exponential distribution based on the given x value and the parameter of the distribution.

Syntax and arguments

Formula syntax

Arguments

Remarks

1. The function returns #VALUE! error value if either argument x or lambda is a non-numeric value.

2. The function returns #NUM! error value if either argument x < 0 or lambda ≤ 0.

3. The equation for the probability density function is:

4. The equation for the cumulative distribution function is:

Version

Excel 2010 and later versions.

Usage and Examples

Basic usage

For instance, the argument x is 2 and the argument lambda is 5, to get the relative cumulative distribution function and probability density function, please use the formula as these:

=EXPON.DIST(2,5,TRUE)  //Return cumulative distribution function

=EXPON.DIST(2,5,FALSE)  //Return probability density function

Press Enter key.
