JEE Math Practice Question
If $$A$$ and $$B$$ are two events such that $$P(A)=\frac{1}{3}, P(B)=\frac{1}{5}$$ and $$P(A \cup B)=\frac{1}{2}$$, then $$P\left(A \mid B^{\prime}\right)+P\left(B \mid A^{\prime}\right)$$ is equal to :
- A.$$\frac{3}{4}$$
- B.$$\frac{5}{8}$$
- C.$$\frac{5}{4}$$
- D.$$\frac{7}{8}$$
