1. A fair coin is tossed repeatedly. Assuming independence of the tosses, find: a. the probability that exactly 3 heads appear in the first 6 tosses; b. the probability that the same number of heads appear in the first 3 tosses as in the next 3 tosses. Q2. A student takes a multiple-choice exam with 12 questions, for which there is one correct answer out of four on each question. If the student randomly guesses on each question, what is the probability the student passes the test if 8 out of 20 is the minimum passing score? Do not use an approximation. Use your statistical tables to find an exact probability
