   Question

   Er is gegeven dat P(A) = 0.4, P(B) = 0.25 en P(A ∩ B) = 0.1. Zijn de gebeurtenissen A en B onafhankelijk?

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