Chapter 5.1 AP Statistics

According to the Book of Odds Web site www.bookofodds.com, the probability that a randomly selected U.S. adult usually eats breakfast is 0.61 which means that...

• 61 people out of 100 eat breakfast

• on average, 61 people out of 100 eat breakfast

• if you asked a large sample of U.S. adults whether they usually eat breakfast, about 61% of them will answer yes.

• 61% of the time, people eat breakfast

If 100 U.S. adults are chosen at random, exactly 61 of them usually eat breakfast.

• true

• false

Probability is a measure of how likely an outcome is to occur.

This outcome is impossible. It can never occur.

• 0

• 0.3

• 0.6

• 1

Probability is a measure of how likely an outcome is to occur.

This outcome is certain. It will occur on every trial.

• 1

Probability is a measure of how likely an outcome is to occur.

This outcome is very unlikely, but it will occur once in a while in a long sequence of trials.

At a local high school, 95 students have permission to park on campus. Each month, the student council holds a “golden ticket parking lottery” at a school assembly. The two lucky winners are given reserved parking spots next to the school’s main entrance. Last month, the winning tickets were drawn by a student council member from the AP® Statistics class. When both golden tickets went to members of that same class, some people thought the lottery had been rigged. There are 28 students in the AP® Statistics class, all of whom are eligible to park on campus.

At the following month’s school assembly, the two lucky winners were once again members of the AP® Statistics class. This raised suspicions about how the lottery was being conducted. How would you modify the simulation in the example to estimate the probability of getting two winners from the AP® Statistics class in back-to-back months just by chance?

Assign the members of the AP® Statistics class the numbers

• 00-99

• 01-28

• 29-95

• 01-95
