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.

0.10

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
