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

A particle with some potential has a wavefunction of [itex]\Psi[/itex]=Axe^{-kx}(from 0 to infinity) if k=.5 what is the prob of finding particle between x=2.0 and 2.1 Angstrom.

2. Relevant equations

P=[itex]\int[/itex] [itex]\Psi[/itex]^{2}

3. The attempt at a solution

I already found what A= in a different problem its 2k^{3/2}

So i thought i would just plug in for A and do the integration from 2 to 2.1. Thats what some example did. i get like .1005 but the answer is .0271.

thanks
