Quizplus · Accepted Answer

The odds of an event happening are defined as the ratio of the probability of the event happening to the probability of the event not happening. For example, if the probability of winning a game is 1/4, then the odds of winning the game are 1:3 (or written as 1/3), which means the probability of losing is 3/4. Therefore, option B is the correct answer.
