Probability Theory Robert J. Blair Trident University International BUS 306 Module 4 Case Assignment Dr. Auden 4 September 2011 Probability Theory 1. A card is drawn at random from a standard 52-card deck. Find the probability that the card is not a queen. 52 card – 4 queens = 48 cards that are not queens. 48/52 = 12/13 or 0.923 = 92.3% probability of not drawing a queen from a standard 52-card deck. 2. Two fair dice are rolled. Find the probability that the sum of the two numbers is not greater than 5. 1+1, 1+2, 1+3, 1+4, 2+1, 2+2, 2+3, 3+1, 3+2, 4+1 are the 10 possible occurrences of two fair dice rolling numbers not greater than 5. With each dice having 6 sides there are 6*6=36 possible outcomes. So there is a 10/36 = 5/18 or 0.625 = 62.5% probability of two fair dice rolling a number combination not greater than 5. 3. This spinner is spun 36 times. The spinner landed on A 6 times, on B 21

Unformatted text preview: times, and on C 9 times. Compute the empirical probability that the spinner will land on B. [pic] A=6, B=21, C=9. The empirical probability of the spinner landing on B is 21/36 = 7/12 or 0.583 = 58.3% 4. If a person is randomly selected, find the probability that his or her birthday is not in May. Ignore leap years. There are 31 days in May and 365 days in a year. 365 – 31 = 334 days that are not in May. 334/365 or 0.915 = 91.5% probability that his birthday is not in May. 5. The chart below gives the number of vehicle tags sold in each city. [pic] One car is selected at random from the cars with vehicle tags from these cities. What is the probability that this car is from Salem? There are 1773 occurrences of a car being from Salem out of a total of 12141 possible outcomes resulting in there being a 1773/12141 = 197/1349 or 0.146 = 14.6% probability the car is from Salem....
