Be best if you ask questions like this in the maths forum, you'll get more answers there!

But for this question, let A be the event that Ann attends the last lecture, and define B,C,D in the same way. So, for example, {A, C} is the event that both Ann and Claire attend the last lecture, but Brian and David do not. To answer the question, run through the possible sets that could occur.
