If A and B are arbitrary events, then

An urn contains 11 balls numbered from 1 to 11. If a ball is selected at random, what is the probability of having a ball with a number which is mutliple of either 2 or 3 ?

The probability that in the toss of two dice we obtain an even sum or a sum less than 5 is

A cricket team has 15 members, of whom only 5 can bowl. If the names of the 15 members are put into a hat and 11 drawn random, then the chance of obtaining an eleven containing at least 3 bowlers is

If $$A$$ and $$B$$ are mutually exclusive events, then $$\displaystyle P\left ( A\cap B \right )$$ equals

The probability that at least one of the events A and B occurs is 0.6, If A and B occur simultaneously with probability 0.2, then $$\displaystyle P\left ( \bar{A} \right )+P\left ( \bar{B} \right )$$ is

A die is thrown. $$A$$ is the event that prime number comes up, $$B$$ is the event that the number divisible by three comes up, $$C$$ is the event that the perfect square number comes up. Then, $$A, B$$ and $$C$$ are :

Two coins are tossed, $$A$$ is the event of getting at most one head, $$B$$ is the event getting both heads, $$C$$ is the event of getting same face on both the coins. The events $$A$$ and $$B$$ are:
