HOMEWORK ASSIGNMENTS FOR STOR 435, SPRING 2010 NOTES: ``Exercises'' refer to *Theoretical Exercises* in the text. Assignments marked ``preliminary'' may have additional problems added later (no problems will be removed). Numbers in square brackets [] refer to problems from the 7'th edition of the text, when there is a difference between the 7th and the 8th. So ``4 [6]'' means that you should do problem 4 if you have the most recent (8th) edition, and do problem 6 if you have the 7th.

Hint for 4: In order to exchange the sums you need to remove the index i from the second sum. To do this, let the second sum run from 1 to infinity, and replace the summand P(N=k) by P(N=k) I(k >= i), where I() is 1 if the statement in () is true, and zero otherwise.
