Find the value of the left side of the schrödinger equation when aψ1+bψ2 is substituted for ψ. to make input easier, use u for u(x) and use the abbreviations −ℏ22md2ψ1dx2=ϕ1 and −ℏ22md2ψ2dx2=ϕ2. express your answer in terms of ψ1, ψ2, ϕ1, ϕ2, a, b, and u.

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.
