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 one.
A) 1/(XY).	B) X/Y.	C) Y/X.	D) 1/(X+Y).	E) 1/(X-Y).
Let the probability of breaking the jar= n   n*1/X = 1/Y   n= X/Y   X/Y. is the answer
