Q. Suppose, in an exam there are two parts in the question paper that are part A and part B. Let us assume that, X and Y represent the marks obtained in part A and part B respectively. The joint distribution of X and Y are given below: Y p(x,y) Y = 0 Y = 5 Y = 10 Y = 15 X = 0 0.02 0.06 0.02 0.10 X = 5 0.04 0.15 0.20 0.10 X = 10 0.01 0.15 0.14 0.01 a. If the total marks are obtained by adding the marks obtained in the two individual parts of the question paper then find the expected marks, E [X,Y]| obtained by a randomly selected student. b. If the maximum marks of the two parts are recorded then what is the expected recorded marks?
