AN EXPERIMENT IS HOW YOU GET A SINGLE CHANCE OUTCOME.
A SAMPLE POINT IS THE MOST BASIC OUTCOME OF AN EXPERIMENT.
THE SAMPLE SPACE IS THE SET OF ALL THE SAMPLE POINTS OF AN
AN EVENT IS A SPECIFIC COLLECTION OF SAMPLE POINTS.
AXIOMS OF PROBABILITY FOR SAMPLE POINTS
IF E IS A SAMPLE POINT
1. 0 # P(E) #1
2. EP(E) = 1
The union of two events is an event that occurs if A or B or both occur. The union consists of all
the sample points that are in A or in B or in both. It is denoted by A c B.
The intersection of two events A and B is an event that occurs if both A and B occur. It consists
of the set of sample points that belong to both A and B. It is denoted by A 1 B.
If two events A and B have no sample points in common they are mutually exclusive.
A 1 B = N and P(A 1 B) = 0.
TheAdditive Rule of Probability
P(A c B) = P(A) + P(B) - P(A 1 B)
The complement of the event A denoted by A is the event that A does not occur.
P(A) + P(A ) = 1
The conditional probability that the
