WebBayes Theorem Bayes Theorem is a formulaic approach to complex conditional probability problems like the last example. However, using the formula is itself complicated, so we will focus on a more intuitive approach. Example 7 Suppose a certain disease has an incidence rate of 0.1% (that is, it afflicts 0.1% of the population).

WebThe preceding formula for Bayes' theorem and the preceding example use exactly two categories for event A (male and female), but the formula can be extended to include more than two categories.
