An event is very unlikely to happen. Its probability is closet to

An event is unlikely to occur. The probability of that event is closer to

If an event cannot occur, then its propbability is

If an event cannot occur, then its propbability is

If 3/10 is the probability that an event will happen, what is the probability that it will not happen

If probability of happening of an event is 5/9 , then the probability of non-happening of this event is:

The probability that an event does not happen in one trial is 0.8 The probability that the event happens atmost once in three trials is

The probability that an event does not happen in one trial is 0.8 The probability that the event happens atmost once in three trials is

An event X can happen with probability P, and event Y can happen with probability P'. What is the probability that exactly one of them happens?
