0.6 = 60% probability that he or she studies on a weeknight.
Step-by-step explanation:
We solve this question treating these events as Venn probabilities.
I am going to say that:
Probability A: Probability of a student studying on weeknights.
Probability B: Probability of a student studying on weekends.
Forty-two percent of students said they study on weeknights and weekends
This means that
47% said they studied on weekends
This means that
65% said they study either on weeknights or weekends.

Considering the values we have:
0.6 = 60% probability that he or she studies on a weeknight.
