| Probability of One Thing Happening: Simple Probability | If there are 27 books on the shelf, what is the probability you'll randomly grab a book with a blue cover if there are 6 books with blue covers? Answer: 6 out of 27 or 6 / 27 reduces to 2 / 9 which is about 22%. | Probability-Part One: Simple Probability | Calculating the probability of an event by creating a ratio | 64-65 | 214--217 | 186-187 | |

| Probability of Multiple Things Happening Together: Compound Probability | If a dice is rolled and a coin is flipped, what is the probability of getting a 6 on the dice and the coin landing on heads? The probability of getting a 6 is 1/6; the probability of getting a heads is 1/2. The probability of both is 1/6 x 1/2 = 1/12. The probability of both events happening is 1/12 or 8.33%. | Probability-Part Two: Compound Probability | Independent and Dependent Probability | 66-67 | 218-219 | 188-189 | |

| Predicting with Probability | If a salesperson makes a sale on 24% of her calls, how many sales should she expect to make if she plans to make 30 calls today? Answer: About 7 (30 x .24 = 7.2) | Making predictions with probability | 68-69 | ||||
