k=18, m9, n=1

In the problems below, please use the following: as k - the sum of digits in your student's number; as m - the largest digit in your student's number; and as n - the smallest digit in your student's number plus 1. Please write down the solutions (transformations, substitutions etc.), and additionally provide the final answer in the space specified (the answer should be a number in decimal notation, rounded to four digits). 25. There are n white balls, m black balls and k green balls in a box. We draw a ball n times, with replacement. Let X and Y denote the number of white and black balls drawn, respectively. Find E(X|Y). Attention. The result is a function of the random variable Y. When providing the final answer, ple- ase expand the additive parts of the expression, simplify them, and express the coefficients in decimal form. Example: if the final answer was = (2-Y) + 10 "Y?(1+2 Y|), it should be expressed as 1.6-0.8Y +0.9Y2+1.8|Y/3. ANSWER: Solution
