ANSWERS
it is the chance of an event occurring - CORRECT ANSWER PROBABILITY
parts of a whole - CORRECT ANSWER PERCENTAGE
0% possibility
Probability that the day of the month will be 32 - CORRECT ANSWER Impossible
1% to 30% probability
A snowstorm in Boston leaves more than 15 inches of snow - CORRECT ANSWER
Unlikely
40% to 60% probability
A pregnant woman having a boy rather than a girl - CORRECT ANSWER As likely as
unlikely
70% to 99% probability
,The probability that a child born in the United States will live to adulthood -
CORRECT ANSWER Likely
100% probability
The probability that everyone alive today has a birthday - CORRECT ANSWER
Certain
probability percentages range strictly from 0% to 100%
Therefore the decimal form of percentages range from 0 to 1 (remember to obtain
the decimal form of a percentage, you divide by 100) - CORRECT ANSWER Decimal
Expression of Percentage
is the procedure, or situation, for which the probability is being calculated.
So the roll of a die can be an experiment, a coin flip can be an experiment, or even
the weather on a particular Wednesday - CORRECT ANSWER EXPERIMENT
The possibilities of what can occur during an experiment—the results of the
experiment—
When rolling a die, 1, 2, 3, 4, 5, and 6 are the possible outcomes - CORRECT
ANSWER OUTCOME
,is comprised of one or more outcomes.
The die landing on an even number is an event. The die landing on 1 is also an
event - CORRECT ANSWER EVENT
if each outcome is equally likely. - CORRECT ANSWER FAIR
The probability of an event is represented by P(E) which means probability (P) of a
certain event (E) occurring.
If R = Rain and the weatherman says there is a 40 percent chance of rain, then
P(R) = 0.40. (Notice that the probability is written in its decimal form). - CORRECT
ANSWER P(E)
FALSE
An experiment is the procedure for which the probability of an event is calculated.
- CORRECT ANSWER . An experiment is the procedure to test the occurrence of an
event. True or False?
TRUE
Each of the possible results from an experiment is known as an outcome. -
CORRECT ANSWER The possible results of an experiment are outcomes. True or
False?
, false
The probability of an event is always between 0% and 100%. - CORRECT ANSWER
The probability of an event occurring can be greater than 100%. True or False?
FRACTIONS
DECIMALS
PERCENTS - CORRECT ANSWER How can probability be expressed in numeric
terms?
flipping a coin
This experiment has an equal probability for each possible outcome. - CORRECT
ANSWER What is an example of a fair experiment?
a collection of unique elements
For example, a set of tree species is: oak, juniper, elm, maple. - CORRECT ANSWER
SET
Set A is a subset* of set B, if every element in A is contained within B.
For example:
