Question

For Q7. – Q10. Imagine you have a party on Sunday and an exam on Monday. Too much food on Sunday could lead to lack of concentration on Monday, which would reduce the probability that you pass the exam. Another consequence of reduced concentration could be stress with your roommate as you forgot to clear the room after dinner! Lack of concentration could also be due to allergy you have after some type of food.


Consider the following random variable that can be either True or False.


A: Too much food on Sunday; B: Allergy strikes; C: Reduced concentration on Monday; D: You pass the exam; and E: Stress with your roommate.


The corresponding Bayesian Network is shown below



Given the above network, state whether the following statements are True or False

1 point

A and B are conditionally dependent if C or any of its descendants i.e., D or E, have received evidence.

True

False

1 point

E is conditionally independent of A, B and D if C is not instantiated.

True

False

1 point

D is conditionally independent of A, B and E if C is instantiated

True

False
