The probability of pulling a black ball out of a glass jar is 1/X. The probability of pulling a black ball out of a glass jar and breaking the jar is 1/Y. What is the probability of breaking the jar? Choose the correct option
A) 1/(XY)
B) X/Y
C) Y/X
D) 1/(X+Y)
E) 1/(X-Y)
Probability of A and B:   When two events are independent, the probability of both occurring is the product of the probabilities of the individual events: P(A and B)=P(A)∗P(B)P(A and B)=P(A)∗P(B)   P(break &amp; black) = P(break) * P(black) --&gt; 1/y=P(break)*1/x --&gt; P(break)=x/y.   Answer: X/Y.
