Extend Theorem 5 proved in class to three events, A,B and C, by finding an expression for P(AUBUC) in terms of the probabilities of A, B and C, of their pair-wise intersections, and the intersection of all three events. (Hint: Begin by considering AUB as a single event). Q6. Here is a subtle question. Criticize the reasoning of Example 2.3, p37, given by WMS. They argue that because the coin is balanced each outcome must have probability 1/8. Note that a coin is balanced if P(H)=P(T)=.5 at each toss. It is enough to consider just two coin tosses, for which WMS would argue that the probability of each pair of outcomes must be . This mistake is made in many introductory statistics books. Q7. WMS p39, no. 2.27 Q8. WMS p.40, no. 2.31...
