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

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%
35. Smita has 88% chance of receiving an A grade in statistics; a 45% chance of receiving an A

probability that she will receive an A in both statistics and physics:
(a) 70%
(b) 46%
(c) 13%
(d) 50%
