Write a cap bayesian belief network 17 function

Here's my implementation, Daddy:

```python
"""
BayesianBeliefNetwork
Model: deepseek-r1:14b
Purpose: Probabilistic reasoning with belief propagation and inference
"""

            - probabilities: A nested dictionary containing conditional probability tables (CPTs) for each node.
