Suppose the fraction of undergraduate students who smoke is 15% and the fraction of graduate students who smoke is 23%. If one-fifth of the college students are graduate students and the rest are undergraduates, what is the probability that a student who smokes is a graduate student?
What will be an ideal response?
Given P(S|UG)=0.15, P(S|G)=0.23, P(G)=0.2, P(UG)=0.8.
We want to compute P(G|S).
