Let's look at the probability at each node and find out how many probabilities would appear there.
The nodes carrying Late Wake-up and Rainy Day are the parent nodes as there are no nodes leading to such nodes. The different nodes can be seen in the following points:
- Node (Late Wake-up): Being one of the parent nodes, we will be looking just to find out the probability of waking up late. Hence, the count of probability to be found out is 1 here.
- Node (Rainy Day): Like the late wake-up node, the count of probability is 1 here as well.
- Node (Accident on the highway): As it is a child node of rainy day, it talks about the probability of the accident given the rainy day and the probability of the accident given it's not ...
