Question 977618: 34. Two students (say A, and B) are challenged to solve a problem in statistics. Suppose that
the probability that A will solve the problem is 40%, the probability that B will solve the
problem is 55%, and the probability that A or B will solve the problem is 25%. The
probability that the problem will be solved (that is both A and B will solve the problem) is
(a) 70%
(b) 95%
(c) 30%
(d) 75%
