1. Write a decision tree to solve the logic of the problem below:               

A student has a problem to decide on where to spend his dinner. Somehow it depends on the following conditions:

If his bank account’s shows that he got > RM 1000; he will go to HYATT hotel special dinner.

If his money is around RM500 and RM1000, then he shall have his dinner at ARENA, JUSCO

If his money  is less than RM500 then he has his dinner at  ‘justanyWarung’

Any other cases, he decides not to have dinner at all.

 

2. A student has to decide whether to drop SCD2613 or continue. This is the condition:

If attendance less than 80% then he better drop the class because he cannot sit for final exam meaning that chances to get an A is zero. Else he may continue but chances to get grade A is not 100% unless he scored in the final exam and did all the homework and project correctly.

Draw the decision tree or table.

 

3. A computer supplies firm called True Disk has set up accounts for countless businesses in KL. True Disk sends out invoices monthly and will give discounts if payments are made within 10 days. The discounting policy is as follows: If the amount of the order for computer supplies is greater than $1,000, subtract 4 percent for the order; if the amount is between $500 and $1,000, subtract a 2-percent discount; if the amount is less than $500, do not apply any discount. All orders made via the Web automatically receive an extra 5-percent discount. Any special order (computer furniture, for example) is exempt from all discounting. Develop a decision table / tree for True Disk discounting decisions, for which the condition alternatives are limited to Y and N.

 

4. A particular flower decides whether to open its petals in the following ways. Draw a decision table to represent the logic of the case below:
