If an event cannot occur, then its probability isQuestion 9Select one:a.0b.3/4 c.1/2d.1

Given that the probability of an event is equal to 0.9, what must be true about the event? Group of answer choicesThe event is impossible.The event is very unlikely to happen.The event is certain to happen.The probability of the event happening and the probability of the event not happening are the same.The event is probable, but not sure to happen.

An event in the probability that will never be happened is called as:Question 2Select one:a.Unsure eventb.Impossible eventc.Sure eventd.Possible event

What is the probability of the following.(a) An event A that is certain to occur?(b) An event B that is impossible?

Given that P(E) = 0.9, what must be true about the event E? Select the best answer.The event E is certain.The event E is possible but not likely.The event E is impossible.The event E is probable but not certain.This is not a valid probability.

If the probability of an event is equal to 1, What must be true about the event?Group of answer choicesThe probability of the event happening and the probability of the event not happening are the same.The event is unlikely but not impossible.The event is impossible.The event is probable but not certain.The event is certain.
