Morphology

conditional + probability

The meaning is directly compositional: 'conditional' = depending on stated conditions and 'probability' = likelihood, so the phrase denotes the likelihood given specific conditions. This adjective+noun composition is cross-linguistically common (e.g., Spanish 'probabilidad condicional') and follows standard patterns, so a B1 learner who knows both constituents should be able to understand it.

Etymology

Conditional probability comes from the simple idea that probability (the 'chance' of something) is changed by a conditional fact you already know. For example, the chance of taking an umbrella is much higher when you know it is cloudy, so the phrase means the chance of an event 'given' that something else has happened.
