Question 18

+2 marksOne correct option

A hospital is conducting a study on enzyme levels (in units per liter, U/L) in blood in adults aged 30–40. Based on historical data 60% of the participants are healthy and 40% have a mild metabolic disorder. Enzyme levels ( ) in healthy individuals follow Normal(50, 36) and for those with the disorder is Normal(60, 25). Based on the above data, answer the given subquestions.

A randomly selected patient from this age group is found to have an enzyme level of 50 U/L.What is the probability that the patient is healthy?
