Bayes Rule Example Problems. Here we are going to see some example problems on bayes theorem. Bayes Theorem Word Problem The following video illustrates the Bayes Theorem by solving a typical problem. 1 The first one is a warm-up problem. Many but not all conditional probability problems in the actuarial exams are of this type.
To evaluate the probability observe that by the multiplication rule From this we have the important Bayes Formula. Here we are going to see some example problems on bayes theorem. 1 The first one is a warm-up problem. Example 1 below is designed to explain the use of Bayes theorem and also to interpret the results given by the theorem. If we have to calculate the probability of taking a blue ball from the second bag out of three different bags of balls where each bag contains three different colour balls viz. You are asked to select one door to find the car.
A screening test accurately detects the disease for 90 if people with it.
1 The first one is a warm-up problem. If A 1 A 2 A 3A n are mutually exclusive and exhaustive events such that P Ai 0 i 123n and B is any event in which P B 0 then Question 1. By design the probabilities of selecting box 1 or box 2 at random are 13 for box 1 and 23 for box 2. If we have to calculate the probability of taking a blue ball from the second bag out of three different bags of balls where each bag contains three different colour balls viz. Behind the doors there are 2 goats and 1 car. For instance a patient is observed to have a certain symptom and Bayes formula can be used to compute the probability that a diagnosis is correct given that observation.
