◉ combination.
Answer: a selection of objects in which order is not important
◉ complement of an event.
Answer: consists of all possible outcomes in a sample space that are
NOT part of the event
◉ conditional probability.
Answer: the probability that an event B occurs after an event A has
already occurred
P(B/A)
◉ dependent events.
Answer: events for which the outcome or occurrence of the first
event affects the outcome or occurrence of the second event in such
a way that the probability is changed
, ◉ empirical probability.
Answer: the type of probability that uses frequency distributions
based on observations to determine numerical probabilities of
events
◉ equally likely events.
Answer: the events in the sample space that have the same
probability of occurring
◉ event.
Answer: A subset of a sample space.
◉ fundamental counting rule.
Answer: In a sequence of n events in which the first one has k1
possibilities and the second event has k2 and the third has k3, and
so forth, the total number of possibilities of the sequence will be
k1 · k2 · k3 · · · kn
Note: In this case and means to multiply.
◉ independent events.
Answer: events for which the probability of the first occurring does
not affect the probability of the second occurring
