Probability of occurrence of an event A+Probability of Non-occurrence of an event A=1.

The probability of the occurrence of an event is 3/7 The probability of non-occurrence of the event is:

The probability of the occurrence of an event is 3/7 The probability of non-occurrence of the event is:

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

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 :

Suppose E and F are two events of a random experiment. If the probability of occurrence of E is 1//5 and the probability of occurrence of F given E is 1//10 . Then the probability of non-occurance of atleast one of the events E and F is

Suppose E and F are two events of a random experiment.If the probability of occurrence of E is (1)/(5) and the probability of occurence of F given E is (1)/(10), then the probability of non- occurrence of at least one of the events E and F is
