The completed truth tables yield the following results:
- For the first table: r=F and q→(r∧p)=F.
- For the second table: ∼b=T, c→∼b=T, b→a=T, and (c→∼b)∧(b→a)=T.
Thus, the final answers are:
- First table: r=F, q→(r∧p)=F
- Second table: ∼b=T, c→∼b=T, b→a=T, (c→∼b)∧(b→a)=T
(r=F,q→(r∧p)=F,∼b=T,c→∼b=T,b→a=T,(c→∼b)∧(b→a)=T)
