Question

08. a) In a locality, out of 5000people residing, 1200 are above 30 years of age and 3000 are females.
suppose after a person is chosen you are told that the person is female what is the probability that she is above the 30 yrs of age?​

Answer 1

Step-by-step explanation:

you need to exclude the overlap first (i.e. females who are over 50).

You can find this by taking 30% of 2000

2000*0.3 = 600

Now add the over 50's, the females, and subtract the overlap and divide by the total population

(1200+2000-600)/6000

2600/6000

26/60

13/30
