A bell curve can be taller than 1, yet no probability ever is. Learn to add up thin slices, and read a density's probabilities from its area rather than its height.

Lesson overview

A bell curve can be taller than 1, yet no probability ever is. Learn to add up thin slices, and read a density's probabilities from its area rather than its height.

What you’ll explore

  • An integral accumulates contributions over an interval; continuous probabilities are areas under a density, and numerical integration approximates that accumulation.
