<u>Answer:</u>
Events A and B are not independent because P(A|B) ≠ P(A).
<u>Step-by-step explanation:</u>
We are given that the probability of a student scoring 75% in class work is 0.64, and the probability of a student scoring 85% is 0.45.
Given that a student scores 85%, it means he must have scored 75% too.
It means that event B is dependent on event A.
Therefore, events A and B are not independent because P(A|B) ≠ P(A).
