1. Consider an experiment that consists of rolling a pair of dice. There are 36 possible outcomes for this experiment which are equally likely. What is the probability of getting a total of 3 or 5 for this experiment? (a) 1 /3 (b) 20/36 (c) 1/36 (d) 1/6 (e) 1/2
2. A car dealer sells cars made by different auto manufacturers. Three of these manufacturers are Honda, Nissan, and Ford. Consider an experiment that consists of observing the make and model of the next car sold. The outcomes in the sample space would include simple events such as Nissan Altima and Ford Fusion. Suppose we define the events E1 = Honda, E2=Nissan, and E3=Ford. Note that E1 is not a simple event because there is more than one model of Honda sold (for example, Civic, Accord, and Insight). Based on several years of sales data, the probabilities of these events are estimated as P(E1) 0.25, P(E2) 0.18, and P(E3) 0.14. Based on this data, what is the probability that the next car purchased is not made by one of these three manufacturers? (a) 0.60 (b) 0.57 (c) 0.43 (d) 0.53 (e) 0.32 2
3. A bookstore sells two types of books (fiction and nonfiction) in several formats (hardcover, paperback, digital, and audio). Consider an experiment that consists of observing the type and format of a single book purchase, two possible outcomes are a hardcover fiction book and an audio fiction book. The number of all outcomes the sample space would include is: (a) 4 (b) 16 (c) 32 (d) 8 (e) 12 4.
