Consider two events such that p(a) = 1/4 , p(b) = 2/3 , and p(a ∩ b) = 1/5 . are events a and b independent events? yes, they are independent because p(a) ⋅ p(b) = p(a ∩ b) no, they are dependent because p(a) ⋅ p(b) = p(a ∩ b) yes, they are independent because p(a) ⋅ p(b) ≠ p(a ∩ b) no, they are dependent because p(a) ⋅ p(b) ≠ p(a ∩ b)
