(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A particle is of mass m has the wave function [itex]\psi[/itex](x)=Ne^{-k|x-a|}with (a>0):

The particle is in the state [itex]\psi[/itex], and its parity is measured. What is the probability to find a positive parity?

2. Relevant equations

None that I can think of...

3. The attempt at a solution

My attempt at a solution is making the leap that this is a qualitative, rather than quantitative question...which leads me to want to say that there is a 50% chance that one would find a positive parity.

Is my assumption that this question wouldn't have a quantitative solution correct? And of course, if it is, did I get the correct reasoning?
