Q. Can we use the Probability Calculator tool if we have data in the form of a percentage?

  1. Yes, you may convert the percentage data into decimal form and then insert it into the respective fields. Likewise, if you need your answer in percentage form, you may convert the decimal answer back to percentage.

Q.  How can we convert odds to a percentage?

  1. First, you need to convert the odds to decimal numbers. Then multiply it by 100. For instance, if the odds are 1 in 8, that's 1/8 = 0.125 in decimal form. Then multiply by 100 to get 12.5%
