Disease X occurs in 1 of every 5,000 people. A new test is developed for the disease, which when tested results in a positive test 2% of the time. If a person has the disease, the test indicates that they do 89% of the time. A random person is tested, and the test comes back positive. Given this positive test, what is the probability they have disease X? Identify P(B|A), P(A) and P(B) and use the Bayes theorem to determine the answer and express your answer as a proportion, rounded to four decimal places provide steps
