Which statement is true about whether A and B are independent events?

A and B are independent events because P(A∣B) = P(A) = 0.16.
A and B are independent events because P(A∣B) = P(A) = 0.75.
A and B are not independent events because P(A∣B) = 0.16 and P(A) = 0.75.
A and B are not independent events because P(A∣B) = 0.75 and P(A) = 0.16.
