1. Are the events mutually exclusive (Yes or No)?

Event A: Randomly select a person between 18 and 24 years old.

2. Decide if the events are mutually exclusive.

Event A: Randomly select a person who uses email.

Event B: Randomly select a person that uses social networking.

Use the table below to answer questions 3-7. The table below shows the number of male and female students enrolled in nursing at a university for a recent semester. Find the specified probability.

Nursing Majors
Nursing Majors Non-Nursing Majors Total
Males 203 1305 1508
Females 841 1498 2339
Total 1044 2803 3847

3. The student is male or a non-nursing major.

4. The student is female or a nursing major.

5. A student is not male or a nursing major.

6. The student is male or a nursing major.

7. Are the events "being male" and "being a nursing major" mutually exclusive?

8. Perform the indicated calculation. 24P5

Use the information below to answer questions 10 - 11. A combination lock has 5 programmable digits. The first digit may be set to whole number values from 1 to 5. The last four digits may be set to whole number values
from 0-9.

10. How many lock combinations are possible if there are no restrictions?

11. What is the probability of selecting a combination code at random that ends with an odd number?

12. Determine if the random variable x is discrete or continuous. Explain the reason for your answer. x is the time required for workers at a factory to complete a task.

15. What is the variance of the probability distribution?

16. What is the standard deviation of the probability distribution?

17. Interpret the results in the context of the real-life situation

18. A state lottery randomly chooses 6 balls numbered 1 from 1 to 40. You choose 6 numbers and purchase a lottery ticket.

The random variable represents the number of matches
on your ticket to the numbers drawn in the lottery. Is this experiment a binomial experiment? Explain your answer.
