**Summary::**How to solve this?

See attached. This is from Griffiths 3rd edition quantum mechanics textbook, problem 2.7:

This is the solution for an infinite square well. I am to find the probability of obtaining E1 where En = n^2pi^2hbar^2/2ma^2.

E1 = hbar^2pi^2/2ma^2

When finding the amplitude of this wavefunction from normalization you will see that it is independent of n. Therefore the probability of measuring E1 is the amplitude squared which is the same for all energy eigenvalues. Is this correct?

Thanks
