The figure shows the probability density for an electron that has passed through an experimental apparatus. What is the probability that the electron will land in a 2.40×10−2-mm-wide strip at:

I'm then asked the probability of finding a particle at various spots on the x-axis. We'll go with x = 0.0 here.

2. P(x)*delta(x) = psi^{2}*delta(x)

3. The big triangle has area 0.5(2mm)(0.5) = 0.5mm^{2}. I then integrated from -1.2*10^{-2}to +1.2*10^{-2}because that width is centered around the 0.0 point of interest. I then evaluated the solution, 0.5x, at the boundaries, obtaining an answer of 0.012... although I don't think I'm going about this quite right.
