The probability of pulling a black ball out of a glass jar is 1/W. 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) E/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/W   Lets say P of breaking the jar = n   That means 1/W*n=1/Y   n= W/Y   E/Y is the answer
<result>B</result>
