If P(A) times P(B) is equal to P(A n B), then that shows the events are independent. Otherwise, they are dependent. When I write "A n B", I mean "A intersect B". The intersect symbol looks similar to the lowercase letter n.
P(A)*P(B) = (3/4)*(2/5) = (3*2)/(4*5) = 6/20 = 3/10
Since that result is not the same as P(A n B) = 1/3, this means that the events are not independent. They are dependent events. The answer is choice D
Elvira already spent $ (78+72+87+90)=$327 on the four orders. The average is $82 so the average is 82x5 =410 . So she has 410-327=83 to spend .
Elvira can spend $83 to keep the average not more than $82
