The probability of pulling a black ball out of a glass jar is 1/R. 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) R/Y C) Y/X D) 1/(X+Y) E) 1/(X-Y)
P of pulling a black ball out of a glass jar AND breaking the jar = 1/Y   P of pulling a black ball out of a glass jar is 1/R   Lets say P of breaking the jar = n   That means 1/R*n=1/Y   n= R/Y   R/Y is the answer
