◉ What is a population? Answer: An entire pool from which a sample is
drawn.
◉ What is a sample space? Answer: The entire set of outcomes for a trial
or experiment.
◉ What is the law of large numbers? Answer: As the number of trials
increases the empirical probability converges on the theoretical
probability.
◉ What is an event? Answer: An outcome, or set of outcomes, whose
chance of occurrence can be represented with a probability.
◉ What is relative frequency? Answer: A 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? Answer: An event that is the opposite of
another event. The probabilities of an event and its complement always
sum to 1.
