Just add 7.44 and 3.82
7.44 + 3.82 = 11.26

C is your possible answer. You are trying to find how many females.
If there just so happens to be that much candy, you probability (Both candies are green) would be 0.2×0.2= 0.04.
Well if you add 14 and 21 you get 35. with 35 you can have 7 groups of 5 but if they have to be equal with the number of boys and girls in each group it would still be 7. two boys in each group with three girls in each group.
