(B) Given the ratio $P(A) : P(\bar{A}) = 3 : 4$.Let $P(A) = 3x$ and $P(\bar{A}) = 4x$,where $x$ is a constant.We know that the sum of the probability of an event and its complement is always $1$,i.e.,$P(A) + P(\bar{A}) = 1$.Substituting the values,we get $3x + 4x = 1$.$7x = 1$,which implies $x = \frac{1}{7}$.Therefore,$P(A) = 3x = 3 	imes \frac{1}{7} = \frac{3}{7}$.
