Answer:
70%
Step-by-step explanation:
Universal set = set of all first year students
P(U) = 1
P(M) = 0.5
P(B) = 0.4
P(M n B) = 0.2
The percent of first year college students take either mathematics or biology or both
P(M U B) = ?
P(M u B) = P(M n B') + P(M' n B) + P(M n B)
P(M n B') = P(M) - P(M n B) = 0.5 - 0.2 = 0.3
P(M' n B) = P(B) - P(M n B) = 0.4 - 0.2 = 0.2
P(M u B) = 0.3 + 0.2 + 0.2 = 0.7 = 70%
