MATH 323 Assignment 1 Due Thursday January 26 by 5pm. Assignments can either be handed in in class on the due date or they can be placed in the counter slot on the 10 th floor of Burnside Hall no later than 5pm on the due date. Late assignments will not be marked. Please ensure that your assignment has on the front page: your printed name, your student number, the course number (MATH 323), and my name as course instructor (David Wolfson). An answer alone is not sufficient. It is important that you give your reasoning in a clear and concise way. This practice is also more likely to ensure that you will get part marks if you get the wrong answer but use the right method. Most questions will be taken from the 7 th edition of Mathematical Statistics with Applications by Wackerley, Mendenhall and Scheaffer, which will be abbreviated to WMS.

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...
