Question
What is the probability of the following.(a) An event A that is certain to occur?(b) An event B that is impossible?
Solution
(a) The probability of an event that is certain to occur is 1. This is because probability is measured on a scale from 0 to 1, where 0 indicates that the event is impossible, and 1 indicates that the event is certain. So, if event A is certain to occur, its probability is 1.
(b) The probability of an event that is impossible is 0. As mentioned above, probability is measured on a scale from 0 to 1. If event B is impossible, meaning it cannot occur under any circumstances, its probability is 0.
