WebMath Probability Let X1, X2, and X3 represent the times necessary to perform three successive repair tasks at a certain service facility. Suppose they are independent, normal rv's with expected values ?1, ?2, and ?3 and variances ?12, ?22, and ?32, respectively. (Round your answers to four decimal places.) WebWell, this particular problem can be solved by thinking in following way: Step 1: First find the total number of solutions in which none of the variables from x1, x2, and x3 is zero. Step 2: Then find the number of solutions in which only one from x1, x2, and x3 is zero. Step 3: Then find the number of solutions in which only two from x1, x2 ...
