Abag contains 4 white, 3 black, and 6 green balls. balls are picked at random. explain why the events picking a white ball and then another white ball without replacement are dependent. then, identify the probability. a. p(white) is different when it is known that a white ball has been picked already. p(white and white) = 4/11 b. p(white) is the same when it is known that a white ball has been picked already. p(white and white) = 1/12 c. p(white) is the same when it is known that a white ball has been picked already. p(white and white) = 1/9 d. p(white) is different when it is known that a white ball has been picked already. p(white and white) = 1/13

An urn contains 3 red, 2 white, and 1 black balls. law and robin take turns and draw balls from this urn one at a time, with no repetition (i.e. drawn balls are not put back in the urn). first person to draw a white ball wins. and if a person draws the black ball, that person loses automatically. assume that all the balls in the urn are equally likely to be drawn at any stage in this game and law is the first person to draw a ball. (a) determine the probability of law winning the game. (b) determine the probability of law winning the game, given that the first ball he drew was red. (c) determine the probability of game ending with someone drawing the black ball. (d) determine the probability of robin drawing the black ball, given that law won the game.
