When a die is rolled once its expected average value =
(1 + 2 + 3 + 4 + 5 + 6)/6 = 3.5
1) So if the Dice is Rolled Twice the most likely sum i.e the most expected sum will be 7 (3.5*2) .
2) Again if the Dice is Rolled Thrice the most likely sum will be 10 or 11 . [Note: As 3.5*3 = 10.5 , the sum cannot be in fraction thus 10 & 11 both will come as the most expected sum ].
3) Again if the Dice is Rolled 4 times the most likely sum will be 14 (3.5*4).

Similarly if A Dies is rolled 14 times and the outcome of every roll is added.What will be the most likely sum = 3.5 * 14 = 49 [Ans]
