(e) P(-1.24<Z<2)=0.8 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: (1) f(x) (e) E(X) (d)) (e) E(Y|X-3) (V(Y|X-3) (8) Are X and Y independent?
