In 1–4, assign truth values to the variables to make the premises true. Then, demonstrate that the arguments are valid by showing that true premises must lead to a true conclusion.
1.
- Premises:
- \( p \rightarrow q \)
- \( q \rightarrow r \)
- \( p \)
- Conclusion:
- \(\therefore r \)
2.
- Premises:
- \( a \lor b \)
- \( b \rightarrow \sim c \)
- \( c \)
- Conclusion:
- \(\therefore a \)
3.
- Premises:
- \( j \rightarrow i \)
- \( \sim j \rightarrow k \)
- \( \sim k \)
- Conclusion:
- \(\therefore i \)
4.
- Premises:
- \( d \land \sim h \)
- \( h \lor y \)
- \( y \rightarrow n \)
- Conclusion:
- \(\therefore n \)
