## Math 113

- Determine a probability based on one event being a certain number of times more likely than
another.
- Determine a probability. Look at problems 3 - 16 in section 3.2.
- Determine which values can be probabilities. Look at problem 1 in section 3.2.
- Find the expected value. Look at problems 13 - 17 in section 4.2*.
- Given a table with frequencies, find probabilities of certain events happening. Look at
problems 17 - 20 in section 3.2. Three parts.
- Find the standard deviation for a binomial experiment. Look at problems 5 - 12 in section
4.4*.
- Set up a binomial problem. Identify success, n, p, q, and x, but do not solve.
- Multiple choice. Know the properties of the binomial distribution.
- Multiple choice. Identify the experiments which could be treated as binomial experiments.
- Multiple choice. Know the properties of probabilities.
- 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.
- Find the mean, variance, and standard deviation of a probability distribution. Look at problems
1 - 12 in section 4.2*.
- Find a binomial probability. Look at problems 11 - 19 in section 4.3*.
- 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 are directly from the textbook.

Problems 1 - 10 must be worked individually. Problems 11 -14 may be worked in pairs.
