## Strategy and Tactics in **Problem** **Solving** - Cut-the-Knot

The resources found on this page offer a new approach to teaching *probability*.

**Probability** **Problem** Solved With Simple Combinations

In these lessons, we will learn how to solve some **probability** word **problems**.

#### Decision Making and **Problem** **Solving**, by Herbert A. Simon

The manual states that the lifetime $T$ of the product, defined as the amount of time (in years) the product works properly until it breaks down, satisfies $$P(T \geq t)=e^, \textrm t \geq 0.$$ For example, the **probability** that the product lasts more than (or equal to) $2$ years is $P(T \geq 2)=e^=0.6703$.

**Probability** is traditionally considered one of the most difficult areas of mathematics, since probabilistic arguments often come up with apparently paradoxical or counterintuitive results.
