Answer:
The answer is the last one - X= 9.9 Y= 7
The probability of the blue (question A) is going to be 0.3535 (C).
The probability of the white (question B) is going to be 0.7455 (D).
-> the probability (that none are white) = (9/12)(8/11)(7/10)(6/9) which = 14/55
the probability (that at least one of them are white) = 1- 14/55 which = 41/55
which makes your answer .7455 (this is the example of the white so you can see how I got the answer)
