Finding probability is easy using the probability formula (the number of favorable outcomes divided by the total number of outcomes). In this article, we'll walk you through exactly how to use the probability formula step by step, plus show you some examples of the probability formula in action. Method 1.
Probability (Event) = Favorable Outcomes/Total Outcomes = x/n. Probability is used to predict the outcomes for the tossing of coins, rolling of dice, or drawing a card from a pack of playing cards. The probability is classified into two types: Theoretical probability. Experimental probability.
This calculator can calculate the probability of two events, as well as that of a normal distribution. Also, learn more about different types of probabilities.

With the probability calculator, you can investigate the relationships of likelihood between two separate events. For example, if the chance of A happening is 50%, and the same for B, what are the chances of both happening, only one happening, at least one happening, or neither happening, and so on.
Probability. How likely something is to happen. Many events can't be predicted with total certainty. The best we can say is how likely they are to happen, using the idea of probability.
How to calculate probability. In order to calculate probability: Identify the sample space. Write out the basic probability. Solve the problem, using \textbf{AND} or \textbf{OR} rules as appropriate.
Define probability including impossible and certain events. Calculate basic theoretical probabilities. Calculate basic empirical probabilities. Distinguish among theoretical, empirical, and subjective probability. Calculate the probability of the complement of an event. It all comes down to this.
Here we will learn how to calculate probability, including basic probability, mutually exclusive events, independent events and conditional probability. There are also calculating probability worksheets based on Edexcel, AQA and OCR exam questions, along with further guidance on where to go next if you’re still stuck.
