PROBABILITY

SOL 6.20

1. NUMBER CUBE

A.How many possible outcomes are there from rolling a number cube?

B.What is the probability for achieving each outcome?

C.Roll a number cube 10 times and record your findings. Is the probability for achieving each outcome the same as in B?

2. COIN

A.How many possible outcomes are there from flipping a coin?

B.What is the probability for achieving each outcome?

C.Flip a coin 10 times and record your findings. Is the probability for achieving each outcome the same as in B?

THEORETICAL PROBABILITY

3. Draw a tree diagram for

rolling number cube and flipping

a coin.

THEORETICAL PROBABILITY

Using the tree diagram, find the following.

4.P(3 and H) 5. P(even, T)

6. P(T and T) 7. P(prime and H)

EXPERIMENTAL PROBABILITY

8. Use a number cube and a coin to explore the

experimental probability. Record your results in a

table.

Trial Number H or T123456789101112

EXPERIMENTAL PROBABILITY

Using the table, find the following.

9.P(3 and H) 10. P(even, T)

11. P(T and T) 12. P(prime and H)

COMPARING THEORETICAL AND EXPERIMENTAL PROBABILITIES

13. Compare your theoretical (#4-7) and experimental (#9 -12)

probabilities.

SAMPLE SPACE

14. Draw a picture to represent the sample space for flipping a coin and rolling a number cube.
