Consider two events such that P(A) = start fraction one over six end fraction , P(B) = start fraction three over five end fraction , and P(A ∩ B) = start fraction two over 15 end fraction full stop . Are events A and B independent events? (4 points)
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)
