Hi, can anyone please help me with this question? I'm quite confused this moment.
In a certain population, containing an equal number of adult males and females, five percent are overweight. Twenty percent of the overweight are female. One person is selected at random from the population. What is the probability that the person is female OR overweight?
Should I try to calculate ? If that's what I should aim for, how do I do it? I'm so confused.
Thanks a lot, I just couldn't work out how to approach before.
I just wonder about one thing please, how do I know it is P(O/F)=0.2, instead of P(F/O)=0.2? From the question wording, it feels like talking about give overweight is condition, then says the females for overweight is 0.2, so should that be P(F/O)=0.2?
Thanks a lot.
