JEE Math Practice Question
It is given that the events $$A$$ and $$B$$ are such that $$P\left( A \right) = {1 \over 4},P\left( {A|B} \right) = {1 \over 2}$$ and $$P\left( {B|A} \right) = {2 \over 3}.$$ Then $$P(B)$$ is :
- A.$${1 \over 6}$$
- B.$${1 \over 3}$$
- C.$${2 \over 3}$$
- D.$${1 \over 2}$$
