Excel - BINOM.INV Function



BINOM.INV Function

The Excel BINOM.INV function is part of the Statistical function and was first launched in Excel 2010. It is used to extract the minimal of the probality_x for which either the cumulative binomial distribution equals the Alpha value or is greater than the Alpha value.

For example, the industry that produces electronic devices has a failure rate of 8%. You can employ the BINO.INV function to determine the small number of electronic devices so that cumulative probability is smaller than or equal to the probability threshold, which is 12%.

Compatibility

This advanced Excel function is compatible with the following versions of MS Excel.

  • Excel for Microsoft 365
  • Excel for Microsoft 365 for Mac
  • Excel for the web
  • Excel 2024
  • Excel 2024 for Mac
  • Excel 2021
  • Excel 2021 for Mac
  • Excel 2019
  • Excel 2016
  • Excel 2013
  • Excel 2010

Syntax

The syntax of the BINOM.INV function is as follows −

=BINOM.INV(trials,probability_s,alpha)

Arguments

You can use the following arguments with the BINOM.INV function −

Argument Description Required/Optional
Trials It denotes the total number of Bernoulli trials. Required
Probability_s It represents a probability of success for each trial. Required
Alpha It indicates a criterion value. Required

Points to Remember

  • If trials argument is in decimal, it will be truncated.
  • If the non-numeric argument is specified in any of the arguments, then the BINOM.INV function will retrieve the #VALUE! error.
  • If trials argument contains a negative value, then BINOM.INV function will retrieve the #NUM! error.
  • The probability_s must be resided between 0 and 1. Otherwise, the BINOM.INV function will retrieve the #NUM! error.
  • If alpha is less than 0 or greater than 1, then the BINOM.INV function will retrieve the #NUM! error.

Examples of BINOM.INV Function in Excel

Practice the following examples to get the master proficiency in the BINOM.INV function in Excel.

Example 1: How to use the BINOM.INV Function in Excel?

In this example, we will explore the usage of the BINO.INV function, which is the inverse of the BINOM.DIST function by supplying the threshold value, the number of independent trials, and X value.

Solution

Step 1 − First, assume the sample dataset where the value of Trails, Probability of Success, Alpha are 12, 0.8 and 0.45.

Therefore, the BINOM.INV function returns the value of 10 as a result.

Example 2

If the non-numeric argument is specified in any of the arguments, then the BINOM.INV function will retrieve the #VALUE! error.

Solution

Step 1 − First, navigate to Sheet 2, select the B2 cell, and type the formula =BINOM.INV("sd","KL", 12).

BINOM.INV Function in Excel 2

Once you hit the Enter, the BINOM.INV function returns the #VALUE! error as the first and second arguments contains text.

BINOM.INV Function in Excel 3

Example 3

If trials argument contains a negative value, then BINOM.INV function will retrieve the #NUM! error.

Solution

First, navigate to the Sheet3, place the cursor on the C2 cell, and, double-click on it, and write the formula =BINOM.INV(-0.34,2, 12) and hit Enter.

BINOM.INV Function in Excel 4

Hence, the BINOM.INV function returns the #NUM! error.

BINOM.INV Function in Excel 5

Example 4

The probability_s must be resided between 0 and 1. Otherwise, the BINOM.INV function will retrieve the #NUM! error.

Solution

You may enter the formula =BINOM.INV(4,23, 12) in the C3 cell and hit Enter.

BINOM.INV Function in Excel 6

Hence, the BINOM.INV function will retrieve the #NUM! error.
