What is a frequency table? - ANSWERSA table which records the frequency of
instances in different categories.
What is a population? - ANSWERSAn entire pool from which a sample is drawn.
What is a sample space? - ANSWERSThe entire set of outcomes for a trial or
experiment.
What is the law of large numbers? - ANSWERSAs the number of trials increases the
empirical probability converges on the theoretical probability.
What is the law of total probability? - ANSWERSA 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? - ANSWERSAn experiment in which all outcomes are equally
likely.
What are disjoint events? - ANSWERSTwo events which cannot both occur at the same
time.
What is a random experiment? - ANSWERSExperiment in which the outcome is not
known ahead of time and in which results do not affect future outcomes.
What is an event? - ANSWERSAn outcome, or set of outcomes, whose chance of
occurrence can be represented with a probability.
What is relative frequency? - ANSWERSA way to approximate a probability by taking
the number of times an event occurs divided by the total number of trials.
What is theoretical probability? - ANSWERSProbability based on equally likely
outcomes.
What is empirical probability? - ANSWERSProbability based on recorded data.
What is a tree diagram? - ANSWERSDiagram showing all events in a sample space.
What are dependent events? - ANSWERSEvents where one affects the other.
