Basic probability (coin flipping, events over trials) by itself is just as useless as basic trigonometry. It only becomes useful as you move from simple combinatorics to continuous distributions, at which point you need differentiation and integration to switch between CDF and PDF. Much in the same way trigonometry becomes useful in physics once you need to deal with vectors and waves.
