(C) Given $P(\bar{B}) = \frac{7}{10}$,so $P(B) = 1 - \frac{7}{10} = \frac{3}{10}$.Using the formula $P(A \cup B) = P(A) + P(B) - P(A \cap B)$,we have $\frac{31}{45} = P(A) + \frac{3}{10} - \frac{1}{6}$.$P(A) = \frac{31}{45} - \frac{3}{10} + \frac{1}{6} = \frac{62 - 27 + 15}{90} = \frac{50}{90} = \frac{5}{9}$.Now,check for independence: $P(A) 	imes P(B) = \frac{5}{9} 	imes \frac{3}{10} = \frac{15}{90} = \frac{1}{6}$.Since $P(A \cap B) = P(A) 	imes P(B) = \frac{1}{6}$,the events $A$ and $B$ are independent.

Let $A$ and $B$ be two events such that $P(A \cap B) = \frac{1}{6}$,$P(A \cup B) = \frac{31}{45}$,and $P(\bar{B}) = \frac{7}{10}$. Then which of the following is true?
