Examine the 'generic' truth table below. It contains truth values for two premises and the conclusion of an argument. Using the information contained in this table, answer the question below: premise (1) 1 T 2 T 3 F 4 F 5 T 6 T 7 F 8 F premise (2) conclusion

Explanation / Answer

If the truth table has a row where the conclusion column is FALSE while every premise column is TRUE, then the argument is INVALID. Otherwise, the argument is VALID.

1) False (because atleast one premise is true and hence conclusion is also true which is valid).

2)False (because by two false it is possible to get a true hence it is valid).

3)False (because it is valid as false false-> false is valid).

4) TRUE (because if both the premises are true the answer should be true. hence it is invalid).
