Open questionGAMCQ1 markNeeds review
Take two long dice (rectangular parallelepiped), each having four rectangular faces labeled as 2, 3, 5, and 7. If thrown, the long dice cannot land on the square faces and has 1/4 probability of landing on any of the four rectangular faces. The label on the top face of the die is the score of the throw.
If thrown together, what is the probability of getting the sum of the two long dice scores greater than 11?
