Problem 2. An engineering statistics class has 40 students; 60% are electrical engineering majors, 10% are industrial engineering majors, and 30% are mechanical engineering majors. A sample of four students is selected randomly without replacement for a project team. Let X and Y denote the number of industrial engineering and mechanical engineering majors, respectively. Determine the following: (a) fxr (x, y) (b) fx(x) (c) E(X) (d) fyp (y) (e) E(Y|X = 3) (f) V(Y | X = 3) (g) Are X and Y independent?
