If probability of a certain event A is P(A) = x, then P'(A) is

If 3/11 is the probability that a certain event will occur, find the odds in favour of its occuring.

The probability of happening of an event is 3/5 . Find the probability of not happening the event.

The probability of happening of an event is 3/5 . Find the probability of not happening the event.

The probability of an event A is (4)/(5) . The probability of an event B, given that the event A occurs is (1)/(5) . The probability of event A, given that the event B occurs is (2)/(3) . The probability that neigher of the events occurs is

The probability of an event A is (4)/(5) . The probability of an event B, given that the event A occurs is (1)/(5) . The probability of event A, given that the event B occurs is (2)/(3) . The probability that neigher of the events occurs is

In two independent events the probability of happening one event is 2/7 and probability of happening of second event is 1/5 . Find the probability of happening of both events.

In two independent events the probability of happening one event is 2/7 and probability of happening of second event is 1/5 . Find the probability of happening of both events.

The probability of occurrence of an event is 2/5 and the probability of non occurrence of another event is 3/10 if these events are independent then the probability that only one of the two events occurs is
