Probability
| Question | Answer |
|---|---|
| complementary events | two events are complements if the sum of their probabilities is 1. (The probability of something happening plus the probability of it NOT happening is 1.) |
| composite events | an event consisting of two or more simple events |
| experimental probability | the ratio of the number of favorable results to the total number of trials in a probability experiment; is based on what DOES happen in an experiment |
| Fundamental Counting Principle | multiplying the number of ways each event in an experiment can occur to find the total number of possible outcomes in a sample space |
| independent event | two or more events in which the outcome of one event does not affect the outcome of the other event |
| sample space | the set of all possible outcomes of a probability event |
| theoretical probability | the ratio of the number of favorable outcomes to the total number of possible outcomes; is based on what should happen under perfect circumstances |
