Problem 5E

In each of the following cases, indicate whether classical, empirical, or subjective probability is used.

a. A baseball player gets a hit in 30 out of 100 times at bat. The probability is .3 that he gets a hit in his next at bat.

b. A seven-membcr committee of students is formed to study environmental issues. What is the likelihood that any one of the seven is chosen as the spokesperson?

c. You purchase one of 5 million tickets sold for Lotto Canada. What is the likelihood you win the $1 million jackpot?

d. The probability of an earthquake in northern California in the next 10 years above 5.0 on the Richter Scale is .80.

Solution :

Step 1 of 4:

Our goal is:

We need to find whether it is classical, empirical, or subjective probability.

a). Given a baseball player gets a hit in 30 out of 100 times at bat.

Then the probability is 0.3 that he gets a hit in his next at bat is empirical.

Therefore, it is empirical.
