MAE 108 – Probability and Statistical Methods for Engineers – Winter 2010 Homework # 2 Assigned: January 13 2010 Due: January 20 2010, in class. Each problem is worth 10 points. 1. Show the following properties (a) If E F then P ( E ) P ( F ) (b) If you have n events E i , then P ( i E i ) i P ( E i ) [Note: i E i = E 1 E 2 ... E n ] [Hint: you can show this by recurrence, i.e assume it’s true for n events, and then show it is true for
