For the first excited state of a Q.H.O., what is the probability of finding the particle in -0.2 < x < 0.2

2. Relevant equations

Wavefunction for first excited state:Ψ= (√2) y e^{-y2/2}

where:

3. The attempt at a solution

To find the probability, I tried the integral of :|Ψ|^{2}

but this gives the integral of gaussian. From what I've read, the integral of a gaussian can only be solved from -infinity to infinity. So how can I find it from -0.2 to 0.2?
