An urn contains one white chip and a second chip that is equally likely to be white or black. a chip is drawn at random and returned to the urn. then a second chip is drawn. what is the probability that a white appears on the second draw given that a white appeared on the first draw? (hint: let wi be the event that a white chip is selected on the ith draw, i = 1, 2. then p(w2|w1) = p(w1∩w2) p(w1) . if both chips in the urn are white, p(w1) = 1; otherwise, p(w1) = 1/2)

How are algebraic expressions evaluated using substitution?

70 points ! pls 2. given the following two sets of data what is the union of the two sets and what is the intersection of the two sets. set a = {1, 2, 3, 4, 5, 6, 7, 8, 9} set b = {2, 4, 6, 8, 10, 12, 14} 3. given a regular deck of cards. describe a way of pulling cards that would create a dependent event and then one that would create an independent event. 4. what is the probability of drawing a red card and then drawing a spade without replacing the card that was drawn first?
