Solution:
(i) The sentence given is a compound statement whose components are
$p$: 2 is a factor of 12
$q$: 3 is a factor of 12
$r$: 6 is a factor of 12
It can can be represented in symbolic function as,
$\text{p }\wedge \text{ q }\wedge \text{ r}$: 2, 3 and 6 are factors of 12.
Solution:
(ii) The sentence given is a compound statement whose components are
$p$: $x$ is an odd integer
$q$: $x+1$ is an odd integer
It can now be represented in symbolic function as,
$p\wedge q$: Either $x$ or $x + 1$ is an odd integer.
