# BINOM.DIST.RANGE function

This article describes the formula syntax and usage of the **BINOM.DIST.RANGE** function (function: A prewritten formula that takes a value or values, performs an operation, and returns a value or values. Use functions to simplify and shorten formulas on a worksheet, especially those that perform lengthy or complex calculations.) in Microsoft Excel.

## Description

Returns the probability of a trial result using a binomial distribution.

## Syntax

BINOM.DIST.RANGE(trials,probability_s,number_s,[number_s2])

The BINOM.DIST.RANGE function syntax has the following arguments.

**Trials**Required. The number of independent trials. Must be greater than or equal to 0.**Probability_s**Required. The probability of success in each trial. Must be greater than or equal to 0 and less than or equal to 1.**Number_s**Required. The number of successes in trials. Must be greater than or equal to 0 and less than or equal to Trials.**Number_s2**Optional. If provided, returns the probability that the number of successful trials will fall between Number_s and number_s2. Must be greater than or equal to Number_s and less than or equal to Trials.

## Remarks

- If any arguments are outside of their constraints, BINOM.DIST.RANGE returns the #NUM! error value.
- If any arguments are non-numeric values, BINOM.DIST.RANGE returns the #VALUE! error value.
- The following equation is used:

- In the equation above, N is Trials, p is Probability_s, s is Number_s, s2 is Number_s2, and k is the iteration variable.
- Numeric arguments are truncated to integers.
