Found inside – Page 13Consider that an event E is a subset that has one or more elements of a sample space. ... To calculate the joint probability of occurrence of two independent events we need to multiply their individual probabilities of occurrence. For example, if a die is rolled, the sample space will be {1, 2, 3, 4, 5, 6} and the event of getting an even number will be {2, 4, 6}. The probability of occurrence of any event lies between 0 and 1. Thus, `P(barE)+P(E)=1` In words, this means that the sum of the probabilities in any experiment is `1`.
