An oil-drilling company knows that it costs $25,000 to sink a test well. If oil is hit, the
income for the drilling company will be $415,000. If only natural gas is hit, the income
will be $130,000. If nothing is hit, there will be no income. If the probability of hitting oil
is 1/40 and if the probability of hitting gas is 1/20, what is the expectation for the
drilling company?

Should the company sink the test well?

When a person in California renews the registration for an automobile, the bar graph
shown below is included with the bill.
Use this bar graph to answer the question. The following statement is included with the
graph.
There is no safe way to drive after drinking. These charts show that a few
drinks can make you an unsafe driver. They show that drinking affects your
BLOOD ALCOHOL CONCENTRATION (BAC). The BAC zones for various numbers of
drinks and time periods are printed in white, gray, and red. HOW TO USE THESE
CHARTS: First, find the chart that includes your weight. For example, if you
weigh 160 lbs., use the "150 to 169" chart. Then look under "Total Drinks" at
the "2" on this "150 to 169" chart. Now look below the "2" drinks, in the row for
1 hour. You'll see your BAC is in the gray shaded zone. This means that if you
drive after 2 drinks in 1 hour, you could be arrested. In the gray zone, your
chances of having an accident are 5 times higher than if you had no drinks. But
if you had 4 drinks in 1 hour, your BAC would be in the red shaded area . . . and
your chances of having an accident 25 times higher.
Suppose that you are over 18 years of age, weigh 155 pounds and have two drinks in 2
