Bayes’ Theorem
// x: prior probability
// y: probability of occurrence, given hypothesis is true
// z: probability of occurrence, given hypothesis is false
bayes = (x, y, z) => (x * y) / ((x * y) + z * (1 - x))
// you come home to find another person's underwear on your bed. is your spouse cheating?
cheating = bayes(0.04, 0.5, 0.05)
