You are correct, but the hope is that the probabilities involved stay low enough that a linear approximation is reasonable. Using for example https://ââwww.microcovid.org/ââ, typical events like a shopping trip carry infection risks well below 1% (dependent on location, duration of activity and precautions etc.).
