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.

If on=8x-8,lm=7x+4,nm=x-5,and ol=3y-6

Use the squared identities to simplify sin^2x cos^2x
