Problem about measurement and probability of energy

Tags:

    1. The problem statement, all variables and given/known data

    2. Relevant equations

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

    3. 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.
