Let denote the complement of an event . Let be pairwise independent events with and . Then equals

Two fair dice are rolled. Let be the event that the first die shows an even number and be the event that the second die shows an odd number. The two events and are:

unbiased die are thrown independently. is the event such that the number on the first die is greater than the number on the second die. is the event such that the number on the first die is even and number on the second die is odd. is the event such that first die shows odd number and second die shows even number, then

Events and are independent. Find , if and

If and are two independent events such that , and , then find the value of :

Given that the events and are such that , and . Find if the events are independent.

Out of a pack of ten cards numbered to a boy draws a card at random and keeps it back. Then a girl draws a card at random from the same pack. If the boy's card reads and the girl's card reads then what is the probability that , given that is even

On rolling a dice times probability of event of obtaining even number and event of obtaining prime numbers are mutually independent or dependent?

If and are two independent events, then the probability of occurrence of at least one of and is given by

Prove that if and are independent events, then so are the events and .

An unbiased die is thrown twice. Let the event be 'odd number on the first throw' and the event 'odd number on the second throw'. Check the independence of the events and .

A die is thrown. If is the event 'the number appearing is a multiple of and be the event 'the number appearing is even' then find whether and are independent?

If and are independent events such that and (Exactly one of and ), then
