Suppose the probability of a student takes ap calculus as is on the honor roll is 0.0035, and the probability that a student is on the honor roll is 0.23. find the probability that a student takes ap calculus given that he or she is on the honor roll.

Find the probability of the students that took the calculus can be on the honor roll.
0.0035 => probability of students that take the AP Calculus
0.23 => probability of the students that can be on the honor roll

Let’s find the solution:
x = probability of the students that took the calculus can be on the honor roll.
=>  x = 0.0035 / 0.23
=>  0.015
Thus, there is 0.015 probability that the students who took the AP Calculus can be on honor roll.

This is a question about conditional probability.
