Homework 2, ECE302, Spring 2013, Prof. Boutin

Due Monday January 28, 2013 (in class)

As for homework 1, this homework consists in handing in the problems that you were asked to solve after each lecture. For convenience, the problems are listed (again) below. Hand in a hard copy of your solutions in class. Make sure to include a cover page and to staple all the pages together. Write legibly and clearly. Put the problems in order. Do not write on the back of the pages. Do not use paper torn out of a spiral book. Thank you very much.

• Problem 2.62 from the textbook: Probability, Statistics, and Random Processes for Electrical Engineering, 3rd Edition, by Alberto Leon-Garcia, Pearson Education, Inc., 2008.

• Problems 14, 15, 16, 17, 18, 24, 25 30, 31, 32, 33 34 from Chapter 1 of "Introduction to Probability," by Dimitri P. Bertsekas and John N. Tsitsiklis. Athena Scientific, Belmont, Massachusetts, 2008.

Questions/comments/Discussion=

• For Problem 16, should we assume each of the 3 coins (double heads, double tails and heads-tails) are un-biased? or do we give them each a variable for their individual biases? - a. willats

EDIT - I suppose this only actually matters for the heads-tails coin

• • Yes, assume that the coins are unbiased. -pm

• For problem 25, it seems like the chances of X being larger than the amount in the envelope are incredibly low, especially as the value in the envelope rises. Wouldn't the final probability depend on the values that exist in the envelopes? If not, what is wrong with our thought process?

• • answer here.
