$P(A \cap B ) = \large\frac{1}{6}$

$P(\overline A \cap \overline B ) = \large\frac{1}{3}$

$ \Rightarrow P(A)\: P(B) = \large\frac{1}{6}$

$P(\overline{A \cup B} ) = \large\frac{1}{3}$

$P(A \cup B ) = 1-\large\frac{1}{3}$

$ = \large\frac{2}{3}$

$ \therefore P(A)+P(B) - P( A \cap B ) = \large\frac{2}{3}$

$ \Rightarrow P(A) + P(B) = \large\frac{2}{3}+ \large\frac{1}{6}$

$ = \large\frac{5}{6}$

Solving (1) and (2) $ P(A) = \large\frac{1}{2}$

$P(B) = \large\frac{1}{3}$

$P(A) = \large\frac{1}{3}\: P(B) = \large\frac{1}{2}$

Ans : (A)
