Math 113: Study Guide Chapters 3 - 4
- Find the probability of an event happening given the likelihood that it will happen in
comparison to the likelihood that it won't. For example - if a "six" is twice as likely to appear
on a single roll of a die as any other number is, then the probability of rolling a "six" is 2/7.
- Find a probability. Look at problems 3.2.3 - 3.2.15.
- Identify which values can be probabilities. Look at problem 3.2.1.
- Find the expected value. Look at problems 4.2.13 - 4.2.14.
- Find probabilities as relative frequencies given observed frequencies. Look at problems
3.3.13 - 3.3.24.
- Find the mean and standard deviation of a binomial distribution. Look at problems 4.4.5 -
- Setup a binomial probability problem. Use the calculator and the binomial program to find
the answer. Identify success (this is an English statement), n, p, and x. Look at problem
- Know the properties of the binomial distribution. Multiple choice.
- Be able to identify a binomial experiment. Look at problems 4.3.1 - 4.3.2. Multiple choice.
- Know the properties of probabilities. Multiple choice.
- Work a Punnet square problem. The table is set up and the terminology is explained for those
who are unfamiliar with the concept. Then answer probability questions based off of the
- Find the mean, variance, and standard deviation of a probability distribution. Look at
problems 4.2.1 - 4.2.12.
- Find a binomial probability. Look at problem 4.3.11.
- Find the mean and standard deviation of a binomial experiment. Then determine if a
particular outcome is unusual. Look at problems 4.4.13 - 4.4.20*.

- Problems 1 - 10 must be worked individually.
- Problems 11 - 14 may be worked in a group of up to three people.
