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.

Which inequality comparing two of the expressions is true when 0.7 < x < 0.9

Sum is 17 and their difference is 3
