   Question

   Van twee gebeurtenissen A en B is het volgende gegeven: P(A) = 0.60, P(B) = 0.40, P(A ∩ B) = 0.20 en P(A ∪ B) = 0.80. Zijn de gebeurtenissen A en B onafhankelijk?

   
   
   1. FALSE: Ja, want P(A ∪ B)= P(A) + P(B) - P(A ∩ B)
   2. FALSE: Ja, want P(B | A) = P(B)
   3. TRUE: Nee, want P(A ∩ B) ≠ P(A) x P(B)
   4. FALSE: Nee, want P(A ∪ B) ≠ P(A) + P(B)
   
   
   1. Ja, want P(A ∪ B)= P(A) + P(B) - P(A ∩ B): Incorrect
   2. Ja, want P(B | A) = P(B): Incorrect
   3. Nee, want P(A ∩ B) ≠ P(A) x P(B): Correct
   4. Nee, want P(A ∪ B) ≠ P(A) + P(B): Incorrect
