Note: Homework Hints are given only for the Level 1 and Level 2 problems.
However, as you go through the book be sure you look at all the examples in the text. If you need hints for the Level 3 problems, check some sources for help on the internet (see the LINKS for that particular section. As a last resort, you can call the author at (707) 829-0606.
On the other hand, the problems designated “Problem Solving” generally require techniques that do not have textbook examples.

Look in the book to find a statement of each of these properties.
Use the binomial distribution theorem as shown in Example 1.
Use the binomial distribution theorem. See the discussion following the box for binomial experiments.
See Example 1b to see how to handle inequalities like these problems.
See Example 1.
Use the binomial distribution theorem where p is the probability of drawing a red pen and k is the number of people selecting that color.
Let p = 0.2 and let k represent the number of infected leaves, and then use the binomial probabilities.
You need to work Problems 33-37 to answer this question.
These applications use the binomial distribution theorem. Look at Examples 3 and 4 for some help on how to set up these problems.
