Computer Datamining Question

5 marks] We have the following Bayesian Belief Network S-Yes FH-YesFamilyHistory (FH) 0.6 0.3 LC=Yes 0.7 0.45 0.55 0.2 LungCancer (LC), FH-Yes, S-Yes FH=Yes, S-No FH-No, S-Yes PR-Yes LC:Yes | 0.85 |.. PositiveXRay (PR) LC-No 0.45 (a) [2 mlarks] Compute the probability of LC is yes, i.e., P(LC = Yes) (b) 2 marks] Compute the conditional probability of PR being yes when FH and S are yes, i.e., P(PR- Yes|FH = Yes. S = Yes) (c) [1 mark] Suppose that there is a new person Family History Smoker Positive XRay Lung Cancer es Yes Yes Please use Bayesian Belief Network classifier to predict whether this new person is likely to have lung cancer
