In a hospital, there are 300 patients, out of which 120 are female. It is known that out of 120 females, 10% of the patients are below 40 years of age. What is the probability that a patient chosen randomly is below 40 yrs of age given that the chosen patient is a female.
Answer & explanation
Correct answer: option 3
Total no. of patient in the hospital = 300
Male = 180
Female = 120
No. of female patient with age below 40 = 10% of 120
= 12
So, the probability that a patient chosen randomly is below 40 yrs of age given that the chosen patient is a female. = 12/120
= 0.10
