State the addition rule of probability.
The addition rule of probability states that the probability of the intersection of two events A and B is equal to the sum of the probability of event A and the probability of event B.
The addition rule of probability states that the probability of the intersection of two events A and B is equal to the product of the probability of event A and the probability of event B.
The addition rule of probability states that the probability of the union of two events A and B is equal to the product of the probability of event A and the probability of event B.
The addition rule of probability states that the probability of the union of two events A and B is equal to the sum of the probability of event A and the probability of event B, minus the probability of the intersection of events A and B.

The probability of selecting a person who is born left-handed is 0.11, or about 1 in 9. This means that
For every 9 people, exactly 1 person will be left-handed.
As we sample more and more people, the proportion of them who are left-handed will get closer and closer to 0.11.
A sample of 100 randomly selected people will contain exactly 11 left-handed people.
It is almost impossible to select two people in a row who are both left-handed.

Which of the following statements illustrates the Law of Large Numbers?
We roll a die until it lands on four. The first four occurs on the 6th roll so the probability of rolling a four is 1/6.
A population has 9% blue-eyed people. If we sample 100 people, 9% will have blue eyes.
A population of individuals contains 73% that can curl their tongue. The larger the sample size we select, the closer the percentage of people who can curl their tongue gets to 73%.
In a small number of people, the proportion who have a dog is 15%. As we increase the sample size, the proportion of people who have a dog will increase from 15%.
Flip a fair coin and record if it lands heads up. If the first flip is tails, the next flip will likely be heads to make the probability of heads equal to 1/2.
