Cumulative beta probability density function, for the above parameters
=BETADIST(A2,A3,A4,A5,A6)
Result:
0.6854706
§ Remarks
- If any argument is nonnumeric, BETADIST returns the #VALUE! error value.
- If alpha ≤ 0 or beta ≤ 0, BETADIST returns the #NUM! error value.
- If x < A, x > B, or A = B, BETADIST returns the #NUM! error value.
- If you omit values for A and B, BETADIST uses the standard cumulative beta distribution, so that A = 0 and B = 1.
✦ Tips
- This function has been replaced with one or more new functions that may provide improved accuracy and whose names better reflect their usage. Although this function is still available for backward compatibility, you should consider using the new functions from now on, because this function may not be available in future versions of Excel.
- If you omit values for A and B, BETADIST uses the standard cumulative beta distribution, so that A = 0 and B = 1.
⚠ Common Errors
#VALUE!
If any argument is nonnumeric, BETADIST returns the #VALUE! error value.

#NUM!
If alpha ≤ 0 or beta ≤ 0, BETADIST returns the #NUM! error value. If x < A, x > B, or A = B, BETADIST returns the #NUM! error value.
Fix: Enter allowed values
