thanks for help and please answer with very fully detailed explanation

Consider the normalized wavefunction: where the eigenvectors [n) form an orthonormal basis. The expansion coefficients are defined: Cn = -1)" n Consider the operator |5) (2|. What is the expectation value corresponding to this operator for a particle in the state |p)? Select one or more: O a. - -3 5 72 b. 3 5TT2 C. -3 50T 2 O d. - V6 10 n O e. V6 10n
