Morphology

equiprobable = probable (semi-transparent) = equi + probable

The meaning is derivable as 'equal' + 'probable', but 'equi-' is a Latin combining form (not the standalone English 'equal'), so the formation may be only partially obvious to average learners.

Etymology

Equiprobable comes from equi- meaning 'equal' and probable meaning 'likely', so it literally says 'equally likely'. So, if events are equiprobable, they all have the same chance of happening.
