   Roll a pure die once. We define the events A and B as follows:______________.
   * A: the number of eyes is greater than 4.Ê. * B: the number of eyes is divisible by 3.  What then is the intersection of A and B, or A ∩ B?

   
   
   1. TRUE: ∩ B = {6}
   2. FALSE: A ∩ B = {5,6}
   3. FALSE: A ∩ B = {3,4,5,6}
   4. FALSE: A ∩ B = {1,2,3,4,5,6}
   
   
   1. A ∩ B = {6}: Correct
   2. A ∩ B = {5,6}: Incorrect
   3. A ∩ B = {3,4,5,6}: Incorrect
   4. A ∩ B = {1,2,3,4,5,6}: Incorrect
