Experimental Probability
1.
Determining the probability of a coin
landing heads up by actually tossing a
coin several times is an example of
_____.
A. experimental probability
B. theoretical probability
C. sample probability
D. outcome probability
Hint
The probability of tossing heads is based on
frequencies obtained in an experiment
2. A spinner numbered 1 through 10 is spun 100 times. The results of the
experiment are shown in the table below. What is the experimental
probability of spinning an 8?
A.
B.
C.
D.
Hint
Find the number of times an 8 was spun
during the experiment.
3. A penny is flipped 50 times. The chart below shows the outcomes of the
experiment. What is the experimental probability of the penny turning up tails?
A.
B.
C.
D.
Hint
Count the number of tails, then divide by 50
4. When Maria gets ready for school, she
has three shirts (in blue, green, or red)

B. 12
C. 8
D. 4
Hint
Use a tree diagram to show the sample
space.
Think back. Look at each problem. Make a
