I tend to use \text{ or }. You can learn more on TeXFAQ and in the mathmode guide.

Code: Select all

\documentclass{article}
\begin{document}	
	\begin{equation}
	I(p)= \frac{1}{p} \left(1- \frac{1-p}{K(1-p)}\right) \;\;\; Or \;\;\;	
	 K(P)=\frac{p}{1-(1-p) \;I(1-p)}
			\end{equation}
			\end{document}

That's a bad advice to keep "Or" in math mode, italic math font. That looks like a product of two variables O and r.

It's better to use what Bartman said, \text{ Or }, to have it in upright text font with correct kerning. "Or" is text, and \text is for text in equations. It requires amsmath, but amsmath should be used in any math document anyway.
