Quizplus · Accepted Answer

The odds against an event are calculated as the ratio of the probability of the event not happening to the probability of the event happening. If the probability of an earthquake is 0.01, the probability of no earthquake is 1 - 0.01 = 0.99. Therefore, the odds against an earthquake are 0.99 to 0.01, which simplifies to 99 to 1.
