A diagnostic system is to be made for a dynamo-powered bicycle light using a Bayesian network. The variables are defined below: Variabl e L S F R V B K Value true / false dry, wet, snow true / false true / false true / false true / false true / false Meaning Light is on Street condition Dynamo flywheel worn out Dynamo sliding Dynamo shows voltage Light bulb OK Cable OK The following variables are independent: S, F, B, K. Th following pairs of variables are independent: (R, B), (R, K), (V, B), (V, K) and the following equation holds: P(L | V, R) = P(L|V), P(V |R, S) = P(V | R), P(V | R, F) = P(V | R). Draw the Bayesian network with the given variables in the Causal model.
