A factory produces two types of items: A and B. Items A have a defect rate of 5%, while items B have a defect rate of 10%. If 70% of items produced are of type A, what is the probability that a randomly selected defective item came from type B?
💡 Hint: Consider applying the theorem with both defect rates and prior production proportions.
In a clinical trial, a med shows a 90% treatment response rate. However, 15% of non-responders still show improvement due to external factors. How is this scenario modeled using Bayes’ Theorem to assign probabilities upon observing a response?
💡 Hint: Survey how patient responses lead to refined probabilities regarding treatment efficacy.
