To calculate probability, you'll use simple multiplication and division. Probability equals the number of favorable outcomes divided by the total number of outcomes.

After the first percentage change, the base changes, and the second percentage does not have the same base. Two percentages that have different base values cannot be directly combined by addition!

Sometimes we get values in our Excel sheets in such a way that the % sign is omitted. So instead of the value being 23%, it is 23. Now, you can very easily correct this by editing the cell and adding a % sign at the end.

Click on the "Number" tab in the "Format Cells" dialog box after it opens. Select "Percentage" from the "Category:" list on the left side of the dialog box. Choose how many decimal points you want to include and click "OK" to convert all of the numbers in your selected cell range to percentages.

The formula for calculating the percentage is Percent = Value/Total * 100. For example, if you have a value in cell A2 and want to calculate what percentage that value is of the total in cell B2, you would use the following formula: Percent = A2/B2 * 100. This would give you the answer in percent form.
