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.

F(x)= 4x g(x) =x-1 what is f(x) divided by g(x)

X2 + y 2 = 36 x + y = 6 solve the system of equations.
