Suppose there are 6 red balls and 4 white balls in a urn.
(1) event A={First draw is a white ball}, what is P(A), probability of A?
(2) Now assume we do picking balls one by one without replacement. event B={Second draw is a white ball}, what is P(B), probability of B?
(3) Are A and B independent? Justify your answer.

please explain and do all the steps fully!
