The BINOM.DIST function, known as BİNOM.DAĞ in Turkish, is a statistical function used to calculate the probability of achieving a specified number of successes in a given number of trials with a certain success probability. This function is available in both Microsoft Excel and Google Sheets and is widely used in fields such as finance, engineering, health sciences, social sciences, and even sports analytics.

Syntax and Parameters

The basic structure of the BINOM.DIST function is expressed as follows:

=BINOM.DIST(success_number, trials, success_probability, cumulative)

• success_number: The number of successful outcomes of interest.
• trials: The total number of trials.
• success_probability: The probability of success on each trial.
• cumulative: Determines whether the function calculates the cumulative distribution function (TRUE) or the probability mass function (FALSE).

Practical Scenarios and Solutions

Below are examples of how the BINOM.DIST function can be used in two practical scenarios.

Scenario 1: Marketing Campaign Success

A marketing manager has sent emails to 50 potential customers and believes each customer has a 10% chance of clicking the ad and purchasing the product. The manager wants to calculate the probability that at least 3 customers will respond successfully to the email campaign.

=BINOM.DIST(2, 50, 0.1, TRUE)

This example calculates the probability that 0, 1, or 2 people will purchase the product. However, since the requirement is for “at least 3 customers,” the result must be subtracted from 1:

=1 - BINOM.DIST(2, 50, 0.1, TRUE)

Scenario 2: Quality Control Test

It is estimated that 5 out of every 100 products on a production line are defective. A quality control engineer wants to know the probability that exactly 5 out of 100 randomly selected products are defective.

=BINOM.DIST(5, 100, 0.05, FALSE)

This formula calculates the probability of exactly 5 defective products appearing, with the cumulative parameter set to “FALSE”, as it computes a specific value.

Summary

The BINOM.DIST/BİNOM.DAĞ function not only calculates the likelihood of achieving targeted success numbers under specific trial and success probabilities but also improves decision-making processes in various business and scientific domains. It is particularly valuable in analyzing situations involving uncertainty and in risk assessments. With options for both cumulative and probability mass functions, this function offers solutions tailored to diverse needs.
