What is a population?

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