Answer 2

Answer:

All we have to find the fraction of students who preferred green and go from there.

Subtracting blue and red out of the all students,

1- (1/8+1/4)

1- 3/8

5/8 is the remaining students, in order to find 3/5 of the remaining students, we multiply by 3/5

5/8(2/5) = 3/8

3/8 preferred green, which was 15 students. In order to get 100% of the whole  population (1), we multiply by 8/3:

15(8/3) = 40

40 students were surveyed in total.
