Solution:
Favorable chance of getting 1 when we roll a dice once = 1
Total possible outcome when we roll a dice once = {1,2,3,4,5,6}=6
Probability of getting 1 , when a die that is number cube is rolled once = [tex]\frac{\text{Total favorable outcome}}{\text{Total possible outcome}}[/tex]=[tex]\frac{1}{6}[/tex]
% of getting 1 = [tex]\frac{1}{6}[/tex] × 100= 16.8%
Option (C): 16.8%
