Explanation / Answer
using the table there are 18 students in total
business major = 10
online students = 9
P( online ) = 9/18
P( business major ) = 10 / 18
business and online student = 4
P( business and online students ) = 4 /18
the rule say that
2 events are independtly when P( A and B) = P(A) * P(B)
lets see we have P(businees and online students) = 4/18
P(online) * P(business) = 9/18 * 10/18 = 5/18
conclusion
there are not indepent events
