Suppose you are planning a party, and your objective is to have an enjoyable party for all guests. An outdoor barbecue would be the best but only if the sun shines; rain would ruin the barbecue. On the other hand, you could plan an indoor party. This would be a good party, not as nice as an outdoor barbecue in the sunshine but better than a barbecue in the rain. Of course, it is always possible to forego the party altogether!
Construct an influence diagram and a decision tree for this problem.

The decision tree is continuing support for judgment, that utilizes a tree-like decision model, and its possible effects, such as the chance event results, resources as well as utility costs. It is a way of displaying an automated system containing the only conditional statement of control, and the further discussion can be defind as follows:

To make it pleasant for all guests concerned, the host needs to decide on the course of the barbeque party.
Plan and draw up a decision tree that will show the potential results based on the different site conditions.
The weather conditions that will prevail at the site on that particular day of the party are the factor of concern about the decision.
Start the tree with such a single node the day of the party which will provide a view of the weather.

Please find the diagram in the attachment file.
