At Bison High School, there are 16 students in English Club,least one of the clubs?
16 students in Science Club and 20 students in Math Club.
Of these students, there are 5 students in both the English and
Science Clubs; 6 students in both the Science and Math
Clubs; and 8 in both the English and Math Clubs. If only 2
students are in all three clubs, how many students are in at
Let e = english only; m = math only; s = science only
Let x be number in english and science but not math
Let y be english and math but not science
Let z be science and math but not english
x+2= 5 so x = 3
z+2= 6 so z=4
y+2 = 8 so y = 6
16=x+y+2+e
20=y+z+2+m
16=x+z+2+s
Can you figure out the rest from here?
