Sometimes, you need to calculate probability with your database. You can calculate this probability using Excel. In this article, I will show how to calculate probability in Excel. I will show 3 practical examples here. Hopefully, you will find this article interesting.

## How to Calculate Probability in Excel: 3 Easy Examples

I will show three examples of the procedure to calculate probability in Excel. Follow the steps of every example to learn the procedures to calculate probability in Excel. Moreover, I have added illustrations also to make the procedures more understandable.

### 1. Calculating Sales Probabilities in Excel

Let’s consider a dataset for calculating sales probabilities in Excel. The dataset has two columns B and C called Sales Amounts and Probabilities. I have fixed the lower limit and upper limits 40 & 80 to calculate the probability. Follow the steps given below. Steps:

• First, select the C14 cell. • Then, copy the following formula in the C14 cell:
`= PROB(B5:B10,C5:C10,C12,C13)` • Consequently, you will find the result in the picture given below. ### 2. Calculating Dice Probabilities in Excel

Here, I will calculate dice probabilities in Excel. This is the new dataset for this example. You can see the total number you can find by throwing two dice at a time in every cell of the dataset. In this dataset, you will find another table having only three columns B, C, and D called Rolls, Chances, and Probabilities. Let’s follow the procedure step by step. Steps:

• Select the C13 cell first. • After that, copy the following formula in the selected cell.
`=COUNTIF(\$C\$5:\$H\$10,B13)`

Here,

• The COUNTIF function will count the required number in cell B13 in the whole dataset ranging from C5 to H10. • Then, press Enter.
• Consequently, you will find the answer in the picture given below.
• Then, Fill Handle the formula from C13 to C23. • After that, you will get the chances column filled with values. • Now, copy the following formula in the D13 cell and Fill Handle the formula from D13 to D23.
`=C13/36`

Here,

• 36 is the total dataset value. • As a result, you will find the Probabilities of Dice Rolls. ### 3. Probability Calculation in Excel Without Using PROB Function

In this example, I will show the probability calculation without the PROB function. Let’s take a dataset indicating the ball colors and quantity of two bags called Bag A and Bag B. However, I will also determine the probability of occurrence of every color of the ball. Follow the steps mentioned below to understand the calculations. Steps:

• Select the D6 cell first.
• Then, write down the following formula in the selected cell.
`=C6/\$C\$9`
• After that, press Enter. • Consequently, you will find the probability.
• Then, Fill-handle the formula from D6 to D8. • As a result, you will get the probabilities like the picture given below. • Similarly, write down the following formula in the G6 cell:
`=F6/\$F\$9` • You will get the probability in the G6 cell.
• Copy down the formula from G6 to G8 cell using the Fill Handle. • You will find the probabilities just like the picture given below. • Now I want to find the probability of picking a green ball from Bag A and a yellow ball from Bag B. • So, copy the following formula in the selected cell.
`=D6*G7` • Then, press the Enter
• As a result, you will get the probability in the selected cell. ## Calculating Probability in Excel with Mean and Standard Deviation

Sometimes, to calculate probability in Excel, the requirement occurs to use mean and standard deviation. In this section of this article, I will show how to calculate probability in Excel with Mean and Standard Deviation. I am considering a new dataset containing two columns B and C called Product and Sale. It has the Mean of Sales amount which is 55 and, assuming the standard deviation is 10. I will calculate the probability for x<55. Let’s follow the following steps. Steps:

• First, select the C13 cell. • Then, write down the following formula.
`=NORMDIST(55,C11,C12, TRUE)` • Moreover, press Enter.
• Consequently, you will find the result. ## How to Calculate Conditional Probability in Excel

In this portion, I will show how to calculate conditional probability in Excel. This is an easy way. I will consider a dataset ranging from B4 to E7. Let’s follow the following steps to calculate conditional probability. Steps:

• Select the D10 cell. • Then, copy the following formula
`=C5/C7`
• After that, press Enter. • Consequently, you will find the result. • Now, select the D11 cell.
• Copy the following formula in the D11 cell:
`=D5/D7`
• Press Enter. • As a result, you will find the probability just like the picture given below. ## Things to Remember

• To calculate probability, you need to know the basics of probability first. The PROB function will give you the probable value between some of the probabilities.
