Astudent attends mathematics class with probability of 75%. he attends drama class with probability of 95%. if attending those classes are independent, find the probability that he attends at leat one of those classes

The probability that the student attends at least one of these classes is equal to 1 - the probability that the student attends none of these classes. If P(M) = .65, then P(~M) = .35  where ~ means notIf P(D) = .85, then P(~D) = .15 Then P(~M ∩ ~D) = .35 x .15 = .0525 And P(attending at least one class) = 1-.0525 = .9475 = 94.75%
