Answer» CORRECT answer is (b) 1 To elaborate: A dice has 6 faces. The faces are NUMBERED 1, 2, 3, 4, 5 and 6. When a dice is rolled, there are 6 OUTCOMES. When 2 dice are rolled, possible outcomes are 36 as below: (1,1) (1,2) (1,3) (1,4) (1,5) (1,6) (2,1) (2,2) (2,3) (2,4) (2,5) (2,6) (3,1) (3,2) (3,3) (3,4) (3,5) (3,6) (4,1) (4,2) (4,3) (4,4) (4,5) (4,6) (5,1) (5,2) (5,3) (5,4) (5,5) (5,6) (6,1) (6,2) (6,3) (6,4) (6,5) (6,6). Thus, the sum of 2 dice can be a number between 2 and 72. It can never be 1. |
