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.
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(𝐷|𝑀) , 𝑃(𝑀) ,and 𝑃(𝐷′|𝑀) , solve the following
a. Draw the probability tree for the main situation.
b. Draw the reverse tree for the main situation.
c. Using the main tree, prove all probabilities on the opposite tree.
d. If 𝑃(𝐷|𝑀) = 0.3, 𝑃(𝑀) = 0.1 ,and 𝑃(𝐷′|𝑀) = 0.65 find P(D)
