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 choice:	A) 1/(XY).	B) X/Y.	C) Y/X.	D) 1/(X+Y)	E) 1/(X-Y).
pulling a black ball out of a glass jar and breaking the jar both are independent events.   For 2 independent events, we know, P(a) * P(b) = P(a∩b)   If Prob of pulling a black ball out of a glass jar = P(a) and Prob of breaking the jar = P(b)   1/x * P(b) = 1/y ---&gt; P(b) = x/y   Hence, answer X/Y..
