## Homework Statement

A Particle is described by the normalized wave function

psi(x,y,z) = Ae^(-alpha[x^2 + y^2 + z^2])

Where A and alpha are real positive constants

a)Determine the probability of finding the particle at a distance between r and r+dr from the origin

hint: use the volume of the spherical shell centered on the origin with inner radius r and thickness dr.

b) For what value of r does the probability in part a) have it's maximum value? Is this the same value of r for which |psi(x,y,z)|^2 is a maximum? explain any differences

## Homework Equations

|psi(x)|^2 = 1

## The Attempt at a Solution

Got no idea, like all 4 questions I'm posting any help would be appreciated, as i am completely lost
