Question
If A and B are two events such that 
and 
then A and B are
- dependent events
- independent events
- mutually exclusive events
- mutually exclusive and independent events
Hint:
In this question we have to find what A and B events are if A and B are two events such that and .A and B are two events associated with the same random experiment, then A and B are known as independent events if P (A ∩ B) = P(B) .P(A), dependent events if P(A∩B) = P(A).P(B/A) or P(A∩B) = P(B).P(A/B) and mutually exclusive if P (A ∩ B) =0.
The correct answer is: independent events
As and
P(B)=P (AUB)- P(A) +P (A ∩ B) =
As P(A). P(B)=
So, A and B are independent events.
