The BETADIST function syntax is:

where

x is the value between A and B at which the function should be calculated.

alpha is the first parameter of the distribution, a numeric value greater than 0.

beta is the second parameter of the distribution, a numeric value greater than 0.

A is the lower bound to the interval of x. It is an optional parameter. If it is omitted, the default value of 0 is used.

B is the upper bound to the interval of x. It is an optional parameter. If it is omitted, the default value of 1 is used.

The values can be entered manually or included into the cells you make reference to.
