Answer:
% of students who are female or have green eyes: 51% or 45/88
% of students who are males without green eyes: 49% or 43/88
The sum of these two percentages: 100%
Step-by-step explanation:
Since there were 48 men surveyed and 40 women there were 88 students surveyed in total.
For the first part:
Since the students had to either be female, 40 students, or have green eyes, 5 male students, there would be a total or 45 students who were either female or had green eyes. Or 45/88 = 51%
For the second part:
Since the students had to be male and NOT have green eyes... take the total number of male students, 48 students, and subtract those with green eyes, 5 students, to get a total of 43 male students without green eyes. Or 43/88 = 49%
