What is a frequency table? - correct answerA table which records the frequency of
instances in different categories.
What is a population? - correct answerAn entire pool from which a sample is drawn.
What is a sample space? - correct answerThe entire set of outcomes for a trial or
experiment.
What is the law of large numbers? - correct answerAs the number of trials increases the
empirical probability converges on the theoretical probability.
What is an event? - correct answerAn outcome, or set of outcomes, whose chance of
occurrence can be represented with a probability.
What is relative frequency? - correct answerA way to approximate a probability by
taking the number of times an event occurs divided by the total number of trials.
What is a complement? - correct answerAn event that is the opposite of another event.
The probabilities of an event and its complement always sum to 1.
What is a union? - correct answerThe union of A and B will have all elements in A, all
elements in B, and all elements in both.
What is conditional probability? - correct answerA probability that depends on the
occurrence of an earlier event.
What is the law of total probability? - correct answerA fundamental principle of
probability which states that the product of all branches of a probability tree, added
together equals 1.
What is a fair experiment? - correct answerAn experiment in which all outcomes are
equally likely.
What are disjoint events? - correct answerTwo events which cannot both occur at the
same time.
, What is a random experiment? - correct answerExperiment in which the outcome is not
known ahead of time and in which results do not affect future outcomes.
What is an intersection? - correct answerThe intersection of A and B will have all
elements that are in both A and B.
What is theoretical probability? - correct answerProbability based on equally likely
outcomes.
What is empirical probability? - correct answerProbability based on recorded data.
What is sample size? - correct answerNumber of outcomes in an experiment.
What is a probability tree? - correct answerDiagram showing probability of events.
What is probability? - correct answerChance of an event occurring.
What is an experiment? - correct answerProcedure with defined outcomes.
What is a Venn diagram? - correct answerChart showing relationships between sets.
What are independent events? - correct answerEvents where one doesn't affect the
other.
What is the multiplication rule for independent events? - correct answerP(A and B) =
P(A) x P(B).
What is a tree diagram? - correct answerDiagram showing all events in a sample space.
What are dependent events? - correct answerEvents where one affects the other.
What is a sample? - correct answerSmall quantity of data representing a population.
