   Two events A and B are independent if holds:

   
   
   1. FALSE: P(A ∩ B) = 0
   2. TRUE: P(A ∩ B) = P(A) x P(B)
   3. FALSE: P(A ∪ B) = P(A) + P(B)
   4. FALSE: P(A ∪ B) = P(A) + P(B) - P(A ∩ B)
   
   
   1. P(A ∩ B) = 0: Incorrect
   2. P(A ∩ B) = P(A) x P(B): Correct
   3. P(A ∪ B) = P(A) + P(B): Incorrect
   4. P(A ∪ B) = P(A) + P(B) - P(A ∩ B): Incorrect
