Q2- Answer the following: a) A box having (10) blue balls, (6) red balls, and (4) white balls. (3) balls are drawn respectively, what is the probability that the balls will be of the same color and drawing is without replacement. b) Find the number of ways in which one A, three Bs, two Cs, and one F can be distributed among seven students taking a course in statistics? c) A multiple choice test consists of 15 equations, each permitting a choice of three altematives. In how many different ways can a student check off her answers to these questions? d) Suppose you have two events A and B in 2, P(A/B)- 0.6, P(B)- 0.25, and P(A)-0.7, find P(B/A)?
