WebBayes’ Theorem is often used in medicine to compute the probability of having a disease GIVEN a positive result on a diagnostic test. We will replace $A$ and $A^c$ in the previous formula with $T^+$ and $T^-$ (reprenting a positive and negative test result). We will also replace $B$ with $D^+$, representing having the disease. WebThe Bayes Theorem, a crucial area of probability theory, will be covered in this article. What is Bayes Theorem?
