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.

Cheers,

Taz
