A random process X (t) consists of an ensemble of three functions with emaciated prob- abilities of occurrence: 3:1(t) = 1 with probability 0.35, 3:20,) = t with probability 0.5, and $30) = 2! with probability 0.15. :1) Sketch the rst-order distribution function F(:r, t) at t = 2. 1)) Evaluate E[X(t)] 6) Evaluate Rxxhtg) d) Evaluate the numerical value of the second order distribution 131:1, h; 22, t2) when I] = 2J1 = I and 1'2 =3,t3 =2
