WebbIn simple terms, probability is defined as the chance of getting a possible outcome. Consider that you have a dice and you have to determine the chance of getting 1 as the result. The probability of getting 1 would be 1/6. This is because the total outcomes are 6 and one side of the dice has 1 as the value.
