What is the probability of drawing a white ball?
The probability of selecting a white ball from the first bag and a black ball from the second bag is (4/6)(5/8) = 10/24. The probability of selecting a black ball from the first bag and a white ball from the second bag is (2/6)(3/8) = 3/24.
What is the probability of white?
Then, the probability of non-having a white ball in two attempts is either 56/156=14/39 if you keep the ball outside, or 64/169 if you did put in back in the bag. Meaning that the probability of having at least one white is 25/39, or 105/169, depending on your exact setup.
What is the probability to draw a white ball from bag A if we know that we drew exactly a total of 2 white balls total?
The probability of a white ball in the second pick is 4/7. Total probability of drawing two white balls is 5/8*4/7 (since they are independent events). If you picked a black ball initially, picking another black ball would have a probability of 2/7, on similar grounds , total prob for 2 blacks would be 3/8*2/7.
