Use the Data Given Below to Answer the Following Question(s) $X$

Use the data given below to answer the following question(s) .
In an event $X$ , the probability of rolling a sum of 8 on two dice is $\frac{5}{36}$ while the probability of rolling an 11 is $\frac{2}{36}$ . In another event $Y$ , the probability of rolling a 2 is $\frac{1}{36}$ , the probability of rolling a 9 is $\frac{4}{36}$ , and the probability of rolling a 4 is $\frac{3}{36}$ .
-Which of the following computes the probability of an event P given that event Q is known to have occurred?

A) P(P|Q) = P(P and Q) / P(Q)
B) P(Q|P) = P(Q) - P(P)
C) P(P|Q) = P(Q) - P(P or Q)
D) P(Q|P) = P(P or Q) - P(Q)
