In exercises 11-12, use all the premises to determine the valid conclusion for the given
argument.
1. If it is a theropod, then it is not herbivorous. If it is not herbivorous, then it is not sauropod. It is
a sauropod. Therefore,.
2. If you buy the car, you will need a loan. You do not need a loan or you will make a monthly
payments. You buy the car. Therefore,

Example 4.5
In each argument, use all premises to determine the valid conclusion.
1. We will not go to japan (-j) or we will go to Hong Kong (h). If we visit my uncle (u). then we
will go to Singapore (s). If we go to Hong Kong then we will not go to Singapore.
Solution:
Write the argument in symbolic form.
~jvh
UIS
h→-s
Premise 1
Premise 2
Premise 3
The first premise can be written as j→ h. The contrapositive of the second premise is ~s →~u.
Therefore the argument can be written as
j-h
Interchanging the second and third premises yields
~S1~U
h→-s
j→h
h→-s
~Su
By transitive reasoning the valid conclusion will be ju. Thus the valid conclusion for the
argument is "If we go to Japan, then we will not visit my uncle."
