Is the probability of an element in Set B also being an element in Set A equal to the probability of an element in Set A also being an element in Set B?

(1) Set A consists of all integers from 1 through 5 and Set B consists of all prime numbers less than 10.

(2) Set A consists of all odd numbers between 1 and 10, both inclusive, and Set B consists of all even numbers between 1 and 10, both inclusive.

I think the answer is D, but this isn't a GMAT question at all, each statement claims something totally different, on the GMAT the statements never contradict each other.

(1) Gives us all the elements in set A and B. Sufficient.

(2) Gives us all the elements in set A and B. Sufficient.

D should be correct.

Although I agree with the person above, this wouldn't appear on the gmat.

HI Bunuel,

Could you please provide your comments on statement 1.

I am using A = {1,2,3,4,5} B = {2,3,5,7}.
How the probability can be same.

Please clarify

Thanks

This is a very poor quality question because the statements contradict each other. Don't waste your time on it.
