Hey IB, good to see you again. Here are the solutions to the questions: Question 29: Step 1: Determine the number of scholars who took at least one of tea or coffee. Total scholars N(U) = 500. Scholars who did not take either N((T C)') = 10. The number of scholars who took at least one is N(T C) = N(U) - N((T C)').
