Bayes' Theorem is given by $P (A | B) = \frac{P (B | A) \cdot P (A)}{P (B)}$ . Use a two-way table to write an example of Bayes' Theorem.

Another interesting aspect of statistics and probability that you will encounter in high school and at college is dealing with two-way tables, which is less complex than it really is. You can start with the two-way tables math that you will encounter not only with the equations but with the majority of questions that deal with two-way tables math where you have two categories. If this sounds too complex as you are looking for answers, turn to our examples of two-way tables. The safest bet would be starting with the two-way tables answers that will have both calculation and analysis.
