STAT416: Probability — Spring 2011 Lecture Notes 1 Chapter 1: Sample Space, Equally Likely Sample Points, Combinatorics, Probability Calculations January 11, 2011 1 Introduction to Probability 1.1 Random Experiment, Sample Space & Events Review Example 1 . Define the sample space for each of the following experiments: 1. Toss a coin twice and record the outcomes. 2. Toss a coin three times and record the outcomes. 3. Select two numbers from 0 through 9 and record the outcomes when sampling is with/without replacement. 4. Select a committee of three from 5 professors in a department. 5. Roll a die two times and record the scores. Example 2 . A fair die is rolled twice. Evaluate the following probabilities. A = The scores are the same. B = The sum of the scores is either 7 or 11. C = The sum is odd. D = The product is odd. E = The sum and the product are both odd. Example 3 . 2 eggs in a carton of 12 are bad. If I pick eggs at random for a three-egg omelet, what is the probability that I do not pick a bad egg?
