Proving P(A|B) with Latex: Seeking Help

[brendan]

Hi All,

I'm using the following Latex Pakages


\documentclass[11pt,a4paper]{article}
\usepackage{amsmath}
\usepackage{graphicx}

I need to prove

P(A|B >= 1- ((1 - r) / s)



I was wondering if anyone has or knows of a good Latex template to display the < > = proofs



regards
Brendan

I'm confused, do you want a proof environment? I am doing a project on probability so you can nick my template if you want, might be useful. http://www.bath.ac.uk/~bs250/Project/title.sty (Don't ask why its called title). It has all the macros I need (theorem, proof, definition, etc..) and some shortcuts like \P for $$\mathbb{P}$$.
