IB does this. The IB plans out a students high school courses over at least 2 years. Trust me, I'm in it! Hope that helps!
A financial goal that I have is to have a well-paying job as I get out of high school so I can afford to go to a University of my choice. This way I won't be in crippling debt and have to take out massive student loans. However, inflation as well as taxes will influence this. Income taxes will force me to have to give up some of my hard-earned money, which will significantly reduce the amount of money I actually make.
I hope this helps! :D If so, will you add it as the brainliest? Thanks! :D
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.
