Probabilitry of finding particle between...

Homework Statement

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

Homework Equations

P=$\int$ $\Psi$²

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
