Answer #1

Solution :

Total possible ways to rolled a die twice is 6^2 = 36

The possible outcomes to the sum of the two rolls equals 7 is 6
{(1,6),(2,5),(3,4),(4,3),(5,2),(6,1)}

The probability that the sum of the two rolls equals to 7 is = possible outcomes/total possible ways
= 6/36 = 1/6
= 0.1667
