The Ghana health service requested for a machine learning model to detect the presence of a new disease based on symptoms present in a blood sample. You have been selected to be part of the team responsible for the development of the model. Belo is a block diagram of the system. Inputs Processing Output The accuracy in the output depends on the correct inputs. The model designed is supposed to be evaluated to determine the accuracy and it is supposed to function in a supervised way. Hence the data sets can affect the model and vice versa. Given P(Data|Model) = P(Model|Data)P(Data) or P(D|M) P(M|D)P(D) show that the p(Model) p(M) following statements are true with a formal mathematical proof. Show that P(M|D)[P(D|M')(1-P(M))+(1-P(D|M)P(M))] а. Р(DIM) 1-р(М) b. Р(D) — P(D|M')(1 — Р(M)) + (1— Р(D'/M)Р(М) )
