Answer
Probability is greater for 2 dices .
Work Step by Step
Ways to get a total of 8 with 2 dice rolled = (2,6),(3,5),(4,4),(5,3),(6,3)
Total possibilities with 2 dices = $6^{2}$ = 36
Probability = $\frac{5}{36}$ = 0.138889
Ways to get a total of 8 with 3 dice rolled = (1,1,6),(1,6,1),(6,1,1),(5,2,1),(5,1,2),(2,5,1),(2,1,5),(1,2,5),(1,5,2),(1,3,4),(1,4,3),(4,3,1),(4,1,3),(3,1,4),(3,4,1),(4,2,2),(2,4,2)(2,2,4),(2,3,3),(3,2,3),(3,3,2) = 21 ways
Total possibilities with 3 dices = $6^{3}$ = 216
Probability = $\frac{21}{216}$ = 0.09722
0.138889 $\gt$ 0.09722
