E) 80%
Explanation:
n(M or E) = n(M) + n(E) – n(M and E)
n(M or E) = 40+50-10 = 80
so % of the students who like neither English
nor Mathematics = 100 – 80 = 20%
n(M or E) = n(M) + n(E) – n(M and E)
n(M or E) = 40+50-10 = 80
so % of the students who like neither English
nor Mathematics = 100 – 80 = 20%
