Chapter 5
1.
With a random experiment or a random sample or other random phenomenon (such as a simulation), the
probability
of a particular outcome is the proportion of times that the outcome would occur in a long run
of observations.
2. Different trials of a random phenomenon are
independent
if the outcome of any one trial is not affected
by the outcome of any other trial.
3. For a random phenomenon, the
sample space
is the set of all possible outcomes.
4. An
event
is a subset of the sample space.
5. The
complement
of an event A consists of all outcomes in the sample space that are not in A. It is
denoted by Ac.
6. Two events, A and B, are
disjoint
if they do not have any common outcomes.
7. The
intersection
of A and B consists of the outcomes that are in both A and B.
8. The
union
of A and B consists of outcomes that are in A or B. In probability, “A or B” denotes that A
occurs or B occurs or both occur.
