You can put this solution on YOUR website! Suppose that 20% of females and 10% of.males are unemployed in a city . Consider a group of people in which 40% are females .Randomly draw one.person from the group.
(a)What is the probability that the drawn person is unemployed ?
(0.2*0.4+0.1*0.6) = 0.14
-------------------------------
(b)Given that the drawn person is unemployed ,what is the probability that the drawn person is a female?
P(unemployed | female) = P(unemployed AND female)/P(female) = 0.2/0.4 = 0.5
---------------------------------
(c)Intuitively reason why the answer in (b) is higher than 40% ?
