Dear helper!
I would like the ask the following questions! Could you help me? Thanks
(a) in city X, the proportion of people having a respiratory disease is 0.08. If ten people in city X are randomly selected, find the probability of that
(i) exactly three people have respiratory disease
(ii) more than two people have respiratory disease
(b) in city Y, 16% of new born babies are under weighted. If a new born baby is under weighted, the probability that its mother being a smoker is 0.58, if a new born baby is not under weight, the probability that its mother being a smoker is 0.27
(i) construct a tree diagram to describe these event
(ii) what is the probability that a new born baby is under weighted if its mother is a non smoker
