Q: A certain virus infects one in every 20 people. A test used to detect the virus in a person delivers positive outcome at 85% accuracy for infected persons. Moreover, it provides negative outcome for healthy persons at 95% accuracy. Compute followings: Find the probability that a person has the virus given that his test outcome is positive.Find the probability that a person does not have the virus given that his test outcome is negative.Find the probability that a person has the virus given that his test outcome is negative.Subject/Course: Introduction to Data ScienceNote: Use "Confusion Matrix" technique to solve this question!
