Decision table testing is being performed on transactions in a bank's ATM (Automated Teller Machine) system. Two test cases have already been generated for rules 1 and 4. which are shown below:
Which two of the additional test cases would achieve full coverage of the full decision table (when combined with the test cases that have already been generated for rules 1 and 4)?
Which two of the additional test cases would achieve full coverage of the full decision table (when combined with the test cases that have already been generated for rules 1 and 4)?

Decision table testing is used to analyze combinations of inputs to determine the appropriate outputs, often based on specific rules or conditions.
For the problem statement:
* Rule 1: (Withdrawal = Allowed, Balance = Sufficient, Fast Cash = True, Correct PIN = True)
* Outcome: Transaction = Approved
* Rule 4: (Withdrawal = Allowed, Balance = Sufficient, Fast Cash = True, Correct PIN = False)
* Outcome: Transaction = Declined
The additional test cases are:
* DT1: (Withdrawal = Allowed, Balance = Insufficient, Fast Cash = True, Correct PIN = True)
* Outcome: Transaction = Declined
* DT2: (Withdrawal = Allowed, Balance = Sufficient, Fast Cash = False, Correct PIN = True)
* Outcome: Transaction = Approved
* DT3: (Withdrawal = Allowed, Balance = Insufficient, Fast Cash = True, Correct PIN = False)
* Outcome: Transaction = Declined
* DT4: (Withdrawal = Allowed, Balance = Sufficient, Fast Cash = False, Correct PIN = False)
* Outcome: Transaction = Declined
From the given test cases,DT2covers the scenario where Fast Cash is False, which is not covered in the initial cases.DT3covers the case where Balance is Insufficient and PIN is incorrect.
Combining Rules 1 and 4 withDT2andDT3covers all the scenarios.
