Word or Word Phrase Definition Picture or Example probability 1. Probability is a numerical value between 0 and 1 that measures the likelihood of an event. Actuaries use probability to assess risk and make tables for insurance companies. experimental probability 2. Experimental probability of an event is a measure of the likelihood that an event occurs based on the actual results of an experiment. A team won 6 of their 10 games. The experimental probability of the team theoretical probability Theoretical probability of an event is a measure of the likelihood that the event occurs based on mathematical reasoning. 3. Answers may vary. Sample: The theoretical probability of a penny landing on heads is 12 . outcome 4. An outcome is the possible result of a situation or experiment. One outcome of rolling a number cube is rolling a 5. event 5. An event is an outcome or a group of outcomes. A possible event of choosing two cards from a deck is a king of diamonds and a 2 of clubs. sample space The sample space is all possible outcomes. 6. The sample space for rolling one number cube is {1, 2, 3, 4, 5, 6}. complement of an event 7. The complement of an event consists of all possible outcomes in the sample space that are not part of the event. The complement of rolling an even number on a number cube is {1, 3, 5}. 6 winning is 10 . Prentice Hall Geometry • Teaching Resources Copyright © by Pearson Education, Inc., or its affiliates.
