Look in the book to find a statement of each of these properties.
Make sure you know these formulas, as well as the conditions for which each applies.
Use the property of complementary probabilities.
Since the given events are independent, you can use the multipliplication property
Use the addition property of probability.
Begin with the property of complementary probabilities. Next, be careful to
properly order the operations as shown in Example 6.
Be sure you pay attention to the order of operations. See Example 6.
See the discussion in the subsection entitled "Independent Events."
Use the multiplication property of probability as shown in Example 3.
Use the addition property of probability as shown in Example 5.
The spinning of each wheel is independent of the spinning and stopping of the
other wheels, so you can use the multlipliction property of probability as shown
in Example 3.
Use the result of Problem 36 for the probabilities, and the definition of expectation to calculate the result.
See Example 1.
These are lengthy problems; proceed slowly and look
at Example 2.
See Example 4.
You might enjoy checking the birthday problem simulation:
Use the multiplication property of probability for these problems. In Problem
48 also use the property of complements.
These are both lengthy, but important problems.
Take your time working through the various parts, as shown in Example 7.
Build a tree diagram as shown in Example 8.
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.
There are many sources for homework help on the internet.
