The probability a randomly selected individual in the US earns more than $82,000 per year is 17.6%. The probability a randomly selected individual in the US earns more than $82,000 given that the individual has a bachelor's degree is 31.3%.
A. - Assign letters to each event and write each probability using statistical notation.
B. - Are the events "earned a bachelor's degree" and "earn more than $82,000 per year" independent? Explain what test you used for independence and show all calculations.

Q1)
Consider two events P and Q.
a. Write the general formula used to calculate the probability
that either event P occurs or Q occurs or both occur.
b. How does this formula change if:
i. Events P and Q are disjoint (i.e., mutually exclusive of each
other).
ii. Events P and Q are nondisjoint events that are statistically
independent of each other.
iii. Events P and Q are nondisjoint events that are
statistically dependent of each other.

2. A consumer survey randomly selects 2000 people and asks them about their income and their television-watching habits. The results are shown in the following table. The numbers within the table reflect people in various categories of TV-watching and annual income. As a reward for participation, each person is given a small prize. Then the names are placed in a box and one name is randomly selected to receive the grand prize...

Among 450 randomly selected drivers in the 20-24 age bracket, 9 were in a car crash in the last year. If a driver in that age bracket is randomly selected, what is the approximate probability that he or she will be in a car crash during the next year? Is it unlikely for a driver in that age bracket to be involved in a car crash during a year? Is the resulting value high enough to be of concern to...
