Step-by-step explanation:
In point a:
If the applicant's parents provide written permission and are 16 years old or older.
Solution:
Logical term: [tex]p^s[/tex]
Through parentheses or negation, deny the whole logical expression. e.g.
[tex]\to \sim p^s[/tex]
by using the rule of DeMorgan's:
[tex]\to \sim p \ v \ \sim s \\[/tex]
The following logical expression is the English phrase:
[tex]\text{The applicant not has written permission from his parents or is at most 15 years old}.[/tex]
In point b:
A parent of the applicant has submitted approved permission or the age of 18 years or older.
Logical expression:[tex]p \ v \ e[/tex]
through brackets or negation, refute the entire logical expression.
[tex]\to \sim (p\ v \ e)[/tex]
Apply DeMorgan's law:
[tex]\to \sim p ^ {\sim e}[/tex]
by using the rule of DeMorgan's:
The following logical expression is the English phrase:
[tex]\text{The applicant not has written permission from his parents and is at most 17 years old}.[/tex]
