Calculate Probability as a Percentage Worksheets

How to Calculate the Probability (as a Percentage) - Calculating probability is something students find exceedingly difficult, but it is an essential concept. Be it weather forecasting or predicting outcomes for games, the probability is frequently used in everyday lives. Probability is the likelihood of an event occurring. It is a mathematical calculation that allows businesses to make well-informed decisions. There are two ways you can write a probability. One is in the form of fractions, and the other is in the form of percentages. Whether you want to calculate probability in fractions or percentages, you will need the total number of possible outcomes in the sample space, and the total number desired outcomes. You need to divide the total number of possible outcomes by the total number of desired outcomes. To calculate the probability in the percentage, you can then multiply the fraction with 100 and find the answer.
