you drop the decision$-$analysis course? Suppose you faced the following problem: If you drop the course, the anticipated salary in your best job offer will depend on your current GPA:

Anticipated Salary$|$Drop $=($$$4,000*$ Current GPA$)+$ $$16,000$

If you take the course, the anticipated salary in your best job offer will depend on both your current GPA and your overall score $($on a scale of $0$ to $100)$ in the course:

Anticipated Salary$|$Do Not Drop $=0\mathrm{.}6*($$$4,000*$ Current GPA$)$

$+0\mathrm{.}4*($$$170*$ Course Score

$+$ $$16,000$

The problem is that you do not know how well you will do in the course. You can, however, assess a distribution for your score. Assuming that $90-100$ is an A$,80-89$ is a B$,70-79$ a C$,60-69$ a D$,$ and $0-59$ an F$,$ assess a continuous probability distribution for your numerical score in the course. Use that distribution to decide whether or not to drop the course. Figure $8\mathrm{.}23$ shows your decision tree.n tree.
