(a) A box contains cards numbered $1$ to $22$. Two cards are drawn simultaneously without replacement and their numbers are noted. What is the probability that both numbers are even ? OR (b) If $\text{P}(A) = \frac{3}{8}$, $\text{P}(B) = \frac{1}{2}$ and $\text{P}(A \cap B) = \frac{1}{4}$, find $\text{P}(\bar{A} / \bar{B})$.
