Question 1152396: The University of Metropolis requires its students to pass an examination in college-level mathematics before they can graduate. The students are given three chances to pass the exam; 56% pass it on their first attempt, 64% of those that take it a second time pass it then, and 45% of those that take it a third time pass it then.
