# BETA.DIST

## Content

This function calculates the cumulative beta distribution function.

## Syntax

`BETA.DIST(x, alpha, beta, cumulative, [lower], [upper])`

## Arguments

This function has these arguments:

| Argument | Description |
| -------- | ----------- |
| *x* | [Required] Value at which to evaluate the function, between the values of lower and upper |
| *alpha* | [Required] Alpha parameter of the distribution |
| *beta* | [Required] Beta parameter of the distribution |
| *cumulative* | [Required] A logical value that determines the function form. The function returns the cumulative distribution function if this argument is true. It returns the probability density function if the argument is false |
| *lower* | [Optional] Lower bound of the interval for x; 0 if omitted |
| *upper* | [Optional] Upper bound of the interval for x; 1 if omitted |

## Remarks

If you omit values for *upper* and *lower*, the calculation uses the standard cumulative beta distribution, so that *lower* is zero and *upper* is one.

## Examples

`BETA.DIST(A1,A3,B4,TRUE,1,3)`
`BETA.DIST(2,8,10,TRUE,1,3)` gives the result 0.685470581
