Pedro drives the same route to work on Monday through Friday. His route includes one traffic light. According to the local traffic department, there is a 55% chance that the light will be red.
Explain what this probability means.

the probability is 55% that the light will be red.

he has a 55% chance that the light will be red.

about 55% of the lights will be red.

When Pedro drives to work,

If Pedro drives the same route to work many many times,

A very good professional baseball player gets a hit about 35% of the time over an entire season. After the player failed to hit safely in six straight at-bats, a TV commentator said, “He is due for a hit by the law of averages.”
Comment on the statement.

short term results do not affect the long term probability of the next at bat

The Law of Large Numbers does not agree

the average of 35% should be shown after a reasonable amount of the baseball players at bats

the average of 35% should occur after many many at bats (close to infinity)

the player is due to for a hit or for a score according to the law of averages.

The commentator is actually correct

Is this a valid probability model?
Explain why or why not?

the total of the probabilities for all the sample spaces < 1.0

No, it is not a valid probability model

the total of the probabilities for all the sample spaces > 1.0

Yes, it is a valid probability model

the total of the probabilities for all the sample spaces = 1.0
