   Question

   Two pure dice are rolled at the same time: one red and one green. The number of pips is upward. Below are several events.  Which alternative is a disjoint relationship between events X and Y?

   
   
   1. TRUE: X = at the red die the 3 is above; Y = at the red die the 6 is above.
   2. FALSE: X = at the red die the 3 is above; Y = at the green die the 6 is above.
   3. FALSE: X = the sum of both dice is 4; Y = the red die has one 3.
   4. FALSE: X = the sum of the red and green dice is 5; Y= at the red die the 4 is on top.
   
   
   1. X = with the red die, the 3 is above; Y = with the red die, the 6 is above…: Correct
   2. X = by the red die the 3 is above; Y = by the green die the 6 is above…: Incorrect
   3. X = the sum of both dice is 4; Y = the red die has one 3.: Incorrect
   4. X = the sum of the red and the green dice is 5; Y= at the red die the 4 is above…: Incorrect
