EXPONDIST FUNCTION formula syntax
The EXPONDIST function in Excel is used to calculate the exponential distribution, which is a continuous probability distribution that describes the time between events in a Poisson process. The syntax for the EXPONDIST function is as follows: EXPONDIST(x, lambda, cumulative) - x: This is the value at which you want to evaluate the exponential distribution. - lambda: This is the parameter that represents the average number of events per unit of time. It must be greater than 0. - cumulative: This is a logical value that determines whether to calculate the cumulative distribution function (TRUE) or the probability density function (FALSE). The EXPONDIST function returns the probability of the exponential distribution at a given value (x) or the cumulative probability up to that value, depending on the value of the cumulative argument.
Use Cases & Examples
In these use cases, we use the EXPONDIST function to calculate the probability of an event occurring within a specific time frame, based on the exponential distribution.

FAQ
Frequently Asked Questions
- The EXPONDIST function is used to calculate the exponential distribution for a given set of parameters.
- The EXPONDIST function requires three arguments: x (the value at which to evaluate the distribution), lambda (the parameter of the distribution), and cumulative (a logical value that determines the form of the function).
- To use the EXPONDIST function, you can enter the formula =EXPONDIST(x, lambda, cumulative) in a cell, replacing x, lambda, and cumulative with the appropriate values.
- The cumulative argument in the EXPONDIST function determines the form of the function. If cumulative is TRUE or omitted, EXPONDIST returns the cumulative distribution function. If cumulative is FALSE, EXPONDIST returns the probability density function.
- No, the EXPONDIST function is specifically used for continuous distributions. For discrete distributions, you should use other appropriate functions.
