Opportunity cost is relevant in this situation. Your opportunity basically consists of the full amount of your college expenses plus the money you would've made when you have chosen to work instead of enrolling in school. <u>The opportunity cost of attending college is $260,000.</u>
The potential benefits that even a person, investor, or business forgo while choosing between two possibilities are known as opportunity costs. Opportunity costs can be easily disregarded since they are by nature invisible.
The opportunity cost would be the worth of what you forgo while making a decision among two or more choices. It's a basic principle that applies to both investing and daily life. The opportunity cost in investing would be the amount of cash you can lose by choosing one asset above another.

The probability that students who were randomly selected studied for the test, if they pass it with a B or higher grade is: D. 0.80.
<h3>How to calculate the probability?</h3>
In this exercise, you're required to determine the probability that students who were randomly selected studied for the test, if they pass it with a B or higher grade. Thus, we would apply Bayes's theorem.
- Let S represent studied for.
- Let B represent a score of B or higher grade
Therefore, we need to find P(S|B):

S|B = 0.80.

<u>Complete Question:</u>
At the beginning of the semester, a professor tells students that if they study for the tests, then there is a 55% chance they will get a B or higher on the tests. If they do not study, there is a 20% chance that they will get a B or higher on the tests. The professor knows from prior surveys that 60% of students study for the tests. The probabilities are displayed in the tree diagram.
