[R] Applying glm coefficients (Beginner Question)

Hello,
I am working with a dataset with three variables and one binomial parameter.
The glm function provides coefficients for these three variables, e.g.
-1.5 | 27.2 | -2.9

If I'm not mistaken, $fitted.values gives me an estimate of how likely my
parameter is to be true/1 . I would like to apply these coefficients on
other variables to predict the binomial parameter but I'm not sure how to
make use of them.

To clarify a bit more I'm looking for a formula to calculate the chance that
the parameter is true/1, based on the three variables/coefficients,
something like

-1.5*V1+27.2*V2-2.9*V2

I hope someone understands my awkwardly worded question and is able to help
me out - thanks!
