Answer to Question #58428 in Statistics and Probability for Andrew

Question

the probability of a boy passing english and mathematics tests are a and b respectively. find the probability of the boy falling both tests

Answer 1

If the probability of a boy passing English and Mathematics tests are a and b respectively, then the probability of the boy falling English is (1 - a) and the probability of the boy falling Mathematics is (1 - b), so the probability of the boy falling both tests is P = (1 - a)*(1 - b).
