, Definitions
Probability is the mathematics of chance.
It tells us the relative frequency with which we can
expect an event to occur
The greater the probability the more
likely the event will occur.
It can be written as a fraction, decimal, percent,
or ratio.
, Definitions
1 Certain
Probability is the numerical
measure of the likelihood that
the event will occur.
Value is between 0 and 1. .5 50/50
Sum of the probabilities of all events
is 1.
0 Impossible
, Definitions
A probability experiment is an action through which
specific results (counts, measurements, or responses)
are obtained.
The result of a single trial in a probability experiment
is an outcome.
The set of all possible outcomes of a probability
experiment is the sample space, denoted as S.
e.g. All 6 faces of a die: S = { 1 , 2 , 3 , 4 , 5 , 6 }
