## Math 113

1. Determine a probability based on one event being a certain number of times more likely than another.
2. Determine a probability. Look at problems 3 - 16 in section 3.2.
3. Determine which values can be probabilities. Look at problem 1 in section 3.2.
4. Find the expected value. Look at problems 13 - 17 in section 4.2.
5. Given a table with frequencies, find probabilities of certain events happening. Look at problems 17 - 20 in section 3.2. Three parts.
6. Find the standard deviation for a binomial experiment. Look at problems 5 - 12 in section 4.4.
7. Set up a binomial problem. Identify success, n, p, q, and x, but do not solve.
8. Multiple choice. Know the properties of the binomial distribution.
9. Multiple choice. Identify the experiments which could be treated as binomial experiments.
10. Multiple choice. Know the properties of probabilities.
11. Punnett Square problem. Complete the punnett square and use it to fill in a frequency table. Then use the frequency table to find probabilities. Seven parts.
12. Find the mean, variance, and standard deviation of a probability distribution. Look at problems 1 - 12 in section 4.2.
13. Find a binomial probability. Look at problems 11 - 19 in section 4.3.
14. Find the mean and standard deviation for a binomial experiment. Then decide if the outcome is unusual. Look at problems 13 - 19 in section 4.4.
Problems 1 - 10 must be worked individually. Problems 11 -14 may be worked in pairs.
