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. (Assume that all students who do not pass the first or second time elect to take the test again.)

56% pass first time or 56 out of 100
of 44 left, .64 pass for 28.2
that total is 84.2 students
There are 15.8 students left so 15.8% take the test 3 times.
