Question 2 Consider two boxes. Box A contains 7 blue and 5 red marbles, while box B contains 6 blue and 8 red marbles. A box is selected at random, and 4 marbles are drawn from it at random. Let X = number of blue balls in the sample of 4 marbles. Part a ) Create a python function prob() with only one input variable k , and which for any & e (0, 1, 2, 3, 4 } computes the value of P(X = k). Do NOT round the output values P(X = k).
