Probability is not about odds but a belief in the existence of an alternative outcome. Rational thinking has little to do with risk avoidance, most of it is about rationalizing one's actions by fitting some logic to them.

The book focuses on the application of simple and profound maths to day-to-day life and how not to be deceived by mathematical traps. Dividing one number by another is mere computation. Figuring out what to divide is mathematics.
