Counting The SpotsLogic Level 2
Standard six-sided dice are numbered from 1 to 6 and are designed to have opposite sides add up to 7. (For example, a 3 on the top means a 4 is hidden on the bottom.)
You roll two dice and count the number of spots on ALL visible faces, getting a total of 40. What is the sum of just the top faces?
Clarification: When you roll a dice, there is only 1 face invisible.
