MULTINOMIAL: Google Sheets Formulas Explained

Hello, my fellow marketing enthusiasts! I'm excited to share with you one of the most powerful tools in Google Sheets: the MULTINOMIAL formula. Yes, I know, it sounds intimidating, but don't worry, I'm here to break it down for you.


MULTINOMIAL is a function in Google Sheets that calculates the multinomial coefficient of a given set of numbers. Uh, I know, that doesn't really clear things up for us non-mathematical people, does it? Let me put it simply - it's a formula you use when dealing with probabilities, particularly when you want to know the likelihood of certain outcomes occurring.

Before we dive into how to use the MULTINOMIAL formula, let's take a step back and give an example of its use. Say we're running a marketing campaign aimed at increasing website traffic. We're using multiple tactics such as social media ads, email campaigns, and content marketing. We want to determine the probability of each tactic driving traffic, and the likelihood of them working together.

Here's where MULTINOMIAL comes in handy. By using this formula, we can calculate the probability of a specific combination of tactics driving website traffic. We can also see the probability of each tactic driving traffic on its own.


Now, let's get into the nitty-gritty of using the MULTINOMIAL formula in Google Sheets. The formula takes a set of numbers as an input and calculates the multinomial coefficients. Here's what the formula looks like:

MULTINOMIAL(number1, [number2, ...])

Don't worry if this looks a little confusing - let me break it down for you. The "number1", "number2" etc. refer to the categories you want to analyze. For example, in our website traffic campaign, we would have social media ads, email campaigns, and content marketing as our categories.

Let's say we have 50 social media ads, 100 email campaigns, and 75 content marketing pieces. We would input these numbers into the formula like this:


When you hit enter, Google Sheets will calculate the probability of your categories working together, and the probability of each category driving traffic alone.

Some tips and tricks for using MULTINOMIAL

Now that we have the basics down, it's time for some insider tips to help you get the most out of your MULTINOMIAL experience:

  • Make sure your numbers add up to the total number of trials, or else the formula won't work.
  • You can actually use MULTINOMIAL for more than three categories - just add more numbers separated by commas.
  • The formula can also be used to calculate the number of ways a set of items can be divided into groups.

Wrapping it Up

Well, there you have it - the MULTINOMIAL formula explained in plain English. I hope this helps you take a deeper dive into probability analysis and makes your marketing campaigns even more successful. Remember, don't be intimidated by formulas - they're just tools to help us achieve our marketing goals!
