When a process that results in one and only one of many observations is performed, it is called an experiment.
The result of the performance of an experiment is called an outcome.
The collection of all outcomes for an experiment is called a sample space.
A simple event is an event that includes one and only one of the final outcomes of an experiment.
A compound event is an event that includes more than one of the final outcomes of an experiment.
The experiment of selecting two items from the box without replacement has the following six possible outcomes:
Hence, the sample space is written as
AB, AC, BA, BC, CA, CB
= person is computer literate
person is computer illiterate
The experiment has four outcomes:
LL, LI, IL,
= the selected part is good
= the selected part is defective
The four outcomes for this experiment are:
GG, GD, DG,
= a toss results in a head
= a toss results in a tail
Thus the sample space is written as
HHH, HHT, HTH, HTT, THH, THT, TTH, TTT
