Best ResponseYou've already chosen the best response.2P(draw both jacks) = 1/3*1/3 = 1/9 P(no jacks) = 2/3*2/3 = 4/9 P(1 jack) = 1  1/9  4/9 = 4/9

Best ResponseYou've already chosen the best response.0Probability of taking out one king in one attempt is 1/3 Correspondingly, prob of 'not' taking out a king in another attempt is 2/3 So the total probability of taking out 'just one' king is 2/9!

Best ResponseYou've already chosen the best response.0Getting king from first attempt only = 1/3 * 2/3 = 2/9 Getting king from second attempt = 2/3 * 1/3 = 2/9 Add them up , u get 4/9

Best ResponseYou've already chosen the best response.0@dumbcow: I was thinking whether both are same or different, but yeah, you're right as there is actual time difference, sry!
