Question | Answer |
When the results of one event do not affect another (such as flipping a coin and spinning a spinner) | independent events |
all possible outcomes of an experiment | sample space |
more than one simple event | compound event |
used to organize possible outcomes sequentially | tree diagram |
when actual events take place to determine outcomes (i.e., a number cube is rolled, or a spinner is spun, or a coin is flipped) | experimental probability |
used when more than one outcome is desired (example -- probability for rolling a two or a three on a number cube: 1/6 + 1/6 = 2/6) | addition principle |
all possible outcomes of an event that are NOT desired | complement |
consisting of just one outcome | simple event |
The chances of events happening as determined by calculating results that would occur under ideal circumstances | theoretical probability |
If an event A can occur in m ways and for each of these m ways, an event B can occur in n ways, then events A and B can occur in m ∙ n ways | counting principle |
The number of times an outcome occurs divided by the total number of trials | relative frequency |
To find the probability that two independent events (A and B) occur, multiply their individual probabilities | multiplication principle |
