Prob/stat Test 2

Front 1

Experiment-

Back 1

An act or process of observation that leads to a single outcome that cannon be predicted with certainty.

Front 2

Sample point-

Back 2

Most basic outcome of an experiment.

Front 3

Sample space-

Back 3

The collection of all sample points in a sample space.

Front 4

Event-

Back 4

Specific collection of sample points.

Front 5

Union of two events A and B-

Back 5

the event that occurs if either A or B or both occur on a singer performance of the experiment.

Front 6

Intersection of two events A and B-

Back 6

The event that occurs if both A and B occur on a single performance of the experiment

Front 7

Complement-

Back 7

The complement of an event A is the event that A does not occur- that is the event consisting of all sample points that are not in event A.

Front 8

Mutually exclusive-

Back 8

If the intersection of A and B contains no sample points,that is, if A and B have no sample points in common.

Front 9

Unconditional probabilities-

Back 9

No special conditionsare assumed, other than those that define the experiment

Front 10

Conditional probability0

Back 10

A probability that reflects additional knowledge that might affect the outcome of an experiment.

Front 11

Independent events-

Back 11

If the occurrence of B doesnot alter the probability that A has occurred; that is, events A and B are independent if
P(A|B) = P(A)

also

P(B|A) = P(B)
