If the probability that a student passes Mathematics is 0.7, passes English is 0.6, and passes both is 0.4, what is the probability that the student passes at least one subject?
Correct Answer: Option D
Explanation:
P(Math ∪ English) = P(Math) + P(English) - P(both) = 0.7 + 0.6 - 0.4 = 0.9. This uses the addition theorem to avoid double-counting students who pass both.
