I was reading part of a book which was explaining about the probability of finding a partical on a 1d line.(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\int^{+\infty}_{-\infty}[/tex]P(x) dx = 1

This sounds right because if the line was infinitely long then the partical must be on it.

You can them intergrate between a and b to find the probability of it being in a lenght and if a and b were the same the probability would be 0.

But when you intergrate P(x) dx you get [tex]\frac{Px^{2}}{2}[/tex]

by putting the numbers in you get P[tex]\infty[/tex] - -P[tex]\infty[/tex]

or P[tex]\infty[/tex] + P[tex]\infty[/tex] = P[tex]\infty[/tex]

A probability can't be more than 1. I must be missing something or dealing with the infinities in the wrong way.

(Sorry it looks like P^infinity its P x infinity but I couldn't change it.)
