For an initial screening of an admission test,a candidate is given fifty problems to solve.If the probability that the candidate can solve and problem is (4)/(5), then the probability that he is unable to solve less than two problems is:

Given the probability that A can solve a problem is 2/3 and the probability that B can solve the same problem is 3/5. Find the probability that none of the two will be able to solve the problem.

If it is given that the probability that A can solve the same problem is (3)/(5). The probability that B can solve the same problem is (2)/(3). The probability that at least one of A and B can solve a problem is

Given the probability that A can solve a problem is 2/3, and the probability that B can solve the same problem is 3/5, find the probability that (i) at least one of A and B will solve the problem (ii) None of the two will solve the problem.

A and B try to solve the problem independently. The probability that A solves the problem is (1)/(2) and that B solves the problem is (1)/(3) . Find the probability that : (a) Both of them solve the problem (b) The problem is solved.
