Which operation of probability calculus would be used to determine the probability that there will not be a volcanic eruption in Italy during the next century?

Question

Quizplus · Accepted Answer

To determine the probability that there will not be a volcanic eruption in Italy during the next century, we need to use the negation operation of probability calculus. The negation of an event A represents the event that A does not occur. So, the probability of the negation of A (i.e., not having a volcanic eruption in Italy during the next century) is equal to 1 minus the probability of A (i.e., having a volcanic eruption in Italy during the next century).
