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.
Encryption protects sensitive information is explanation best explains the importance of using encryption. Personal information and important information are protected, and communication between client apps and servers is made more secure.
<h3>What is Encryption?</h3>
Encryption is a way of securing digital data that employs one or more mathematical procedures, as well as a password or "key" to decrypt the information.
Data is encrypted using an algorithm that makes the original data unreadable. The name of two different data comes from the fact that encryption and decryption are done with the same key.
Thus option C is correct.
