Consider a situation in which P(X) = and PLY) = 4 If P(X and Y) is = 1, which best describes the events?

-

They are independent because PIX) PY) = PIX and Y).

They are independent because P(X) + PIY) = P(X and Y).

They are dependent because P(X) PIY) = P(X and Y).

They are dependent because P(X) + P(Y) = PIX and Y).
