In a batch, 40% of the students offered Maths, 30% offered science and 15% offered both. If a student is selected at random, what is the probability that they has offered science or maths? (A) 0.55 (B) 0.65 (C) 0.75 (D) 0.45►Correct Option Correct Option is: AP(M) = 0.40 P(S) =0.30 and P(M∩S) = 0.15 P(M∪S) = P(M) + P(S) – P(M∩S) = 0.55
