The probability that a student uses the Internet, given that he or she is in eighth grade is 8/13 or 0.66
<u>Step-by-step explanation:</u>
<u>From the table shown:</u>
- The students in the eighth grade = 13
- The eighth grade students using internet = 8
P(student uses the Internet in eighth grade) = P(eighth grade students using internet) / P(total students in the eighth grade)
⇒ 8/13
⇒ 0.66
