Use this formula: $\large \sf \color{blue}{[1-e^{(\frac{[X_a-X_b]^2}{4})}] \times 100}$ where $\sf \color{red}{X_a}$ and $\sf \color{red}{X_b}$  is the electronegativity value of the two atoms in question: O and H, respectively.

I forgot to mention, that's using the electronegativity values on the $ pauling$ scale. I know sometimes people use mulken electronegativities for $X$. Just wanted to clarify that.
