How to use the EXPON.DIST function
Author: Oscar Cronquist Article last updated on May 11, 2022
The EXPON.DIST function calculates the exponential distribution representing an outcome in the form of probability.
This function was introduced in Excel 2010, it has replaced the EXPONDIST function which is now outdated.
Formula in cell E3:
=EXPON.DIST(B3,C3,D3)
Excel Function Syntax
EXPON.DIST(x, lambda, cumulative)
Arguments
| x | Required. The value of the function. |
| lambda | Required. The parameter value. |
| cumulative | Required. A boolean value. TRUE - cumulative distribution function. FALSE - probability density function. |
Comments
The EXPON.DIST function returns
- #VALUE! error value if lambda or x is non-numeric.
- #NUM! error value if:
- x < 0 (zero)
- lambda <= 0 (zero)
