# A die marked 1,2,3 in red and 4,5,6 in green is tossed. Let A be the event that “number is even” and B be the event that “number is marked red”. Find whether the events A and B are independent or not.

Answer :

Let A: number is even

B: number is marked red

For A and B to be independent events, P(A∩B)=P(A)P(B)

Since here P(A∩B) ≠P(A)P(B), therefore A and B are not independent events.

If A and B are two independent events such that P(A’ ∩ B) = 2/15 and P(A ∩ B’) = 1/6 then find P(A) and P(B).

If A and B are two independent events then P(A and B) = P(A).P(B)

If A and B are mutually exclusive events, then they will be independent also.

If A and B are independent, then

P (exactly one of A, B occurs) = P(A)P(B′)+P(B) P(A′)

If A and B are independent events, then P(A′ ∪ B) = 1 – P (A) P(B′)

Let P(A) > 0 and P(B) > 0. Then A and B can be both mutually exclusive and independent.
