Term
complement
Definition
complement: all the ways that an event can not happen.

ex: When rolling a number cube, the complement of rolling a 3 is rolling a 1, 2, 4, 5, or 6.
Term
compound event
Definition
compound event: an event made up of two or more simple events.

ex: When tossing a coin and rolling a number cube, the event of the coin landing heads up and the number cube landing on 3 is a compound event.
Term
equally likely
Definition
equally likely: Outcomes that have the same probability.

ex: When you toss a coin, the outcomes “heads” and “tails” are equally likely.
Term
experimental probability
Definition
experimental probability: The ratio of the number of times an event occurs to the total number of trials, or times that the activity is performed.

ex: Kendra attempted 27 free throws and made 16 of them. Her experimental probability of making a free throw is
number made/number attempted
16/27 = 0.59.
Term
outcome
Definition
outcome: A possible result of a probability experiment.

ex: When rolling a number cube, the possible outcomes are 1, 2, 3, 4, 5, and 6.
Term
prediction
Definition
prediction: A guess about something that will happen in the future.
Term
probability
Definition
probability: A number from 0 to 1 (or 0% to 100%) that describes how likely an event is to occur.

ex: A bag contains 3 red marbles and 4 blue marbles. The probability of randomly choosing a red marble is 3/7.
Term
theoretical probability
Definition
theoretical probability: The ratio of the number of equally likely outcomes in an event to the total number of possible outcomes.

ex: When rolling a number cube, the theoretical probability of rolling a
4 is 1/6.
