Probabilities for Electron in a Box (n=1 & n=2)

[Ming0407]

What are the probabilities of finding the electron anywhere between x=0 and x=L/4? (n=1 and n=2)


Can you give example to me?

Do you know the wave function for a particle in a box, or can you try to derive them?

That is the correct wave function. Can you use that to predict the probability in being in one section of the box? Remember that \left|\psi\left(x\right)\right|^2 is a probability density, so you have to integrate over some interval in x (The right interval is specified in your problem, can you spot it?).
