Solve the equation Ax = b by using the LU factorization given for A. A = [ 1 2 3 0 [ 1 0 0 0 -2 -2 -6 12 - 2 1 0 0 3 0 64 -3 3 -3 1 0 -5 -4 -12 37 ] -5 3 -1 1 ] A = [ 1 2 3 0 , b = [17 0 2 0 12 -20 0 0 -3 0 3 0 0 0 1] -34 ]

Successful implementation of a new system is based on three independent modules. module 1 works properly with probability 0.96. for modules 2 and 3, these probabilities equal 0.95 and 0.90. compute the probability that at least one of these three modules fails to work properly.
