20. On an 8-question true or false test, you randomly guess at the answers. What is the probability that you get all 8 answers correct? What is the probability that you get all 8 answers wrong? OA. 1/256; 255/256 OB. 1/256; 1/256 OC. 1/2; 1/2 OD. 1/8, 7/8 21. If A and B are two events associated with the same sample space of a random experiment then P(A/B) is given by OA. P(AMB)/P(B), provided P(B) = 0 OB. P(AMB)/P(B), provided P(B) = 0 OC. P(ANB)/P(B) OD. P(AMB)/P(A) 22. Given that A and B are events such that P(A) = 0.6, P(B) = 0.3 and P(A B) = 0.2, then P(A/B) =? A. 2/3
