The probability of event `A` is `3//4`. The probability of event `B`, given that event `A` occurs is `1//4`. The probability of event `A`, given that event `B` occurs is `2//3`. The probability that neither event 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

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 event A is '(5)/(6)' and probability of event B,given that A occurs is '(2)/(3)'he probability of event A,given that B occurs is '(7)/(9)'.The probability that neither event occurs,is

Define conditional probability of event A, given that event B has occurred.

For an event, odds against is 6 : 5. The probability that event does not occur, is

If A and B are two events, the probability that at most one of these events occurs is

An event has odds in favour 4 : 5, then the probability that event occurs, is

The probability of occurrence of an event A is 5/9 . The probability of non - occurrence of the event B is 5/11 . The probability that at least one of them will occur is :
