Question 1118589: pplicants who wish to be admitted to a certain professional school in a large university are required to take a screening test devised by an educational testing service. From past results, the testing service has established that 70% of all applicants are eligible for admission and that 91% of those who are eligible for admission pass the exam, whereas 14% of those who are ineligible for admission pass the exam. (Round your answers to three decimal places.)

===Pass--------Fail======Total
Eli 6370---------630-------7000
Not 420---------2580------3000
T==6790---------3210------10000
Probability passed is 6790/10000 or 0.679
Probability passed but was ineligible is 420/6790 or 0.0619
