ELEMENTARY STATISTICS FINAL PAPER
FULL QUESTIONS AND CORRECT ANSWERS
ALREADY PASSED
●● 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
●● law of large numbers
