Homework Equations



I solve the (a) , using even,odd function. So, C=1/a

The Attempt at a Solution



I don't know how to approach (b).
I think that 'total energy of the system' doesn't mean expectation value, how can i get
total energy and probability of them?

If you measure the energy, the system can only be found in one of the eigenstates of the Hamiltonian.
