If an original conditional statement is represented by [tex]$p \rightarrow q$[/tex], which represents the contrapositive?

A. [tex]$q \rightarrow p$[/tex]
B. [tex]$\sim q \rightarrow \sim p$[/tex]
C. [tex][tex]$p \rightarrow q$[/tex][/tex]
D. [tex]$\sim p \rightarrow \sim q$[/tex]


Sagot :

When considering a conditional statement [tex]\( p \rightarrow q \)[/tex], it's important to understand the concept of a contrapositive. The contrapositive of [tex]\( p \rightarrow q \)[/tex] is created by reversing and negating both parts of the statement.

To break it down step-by-step:

1. Identify the components:
- [tex]\( p \rightarrow q \)[/tex] is the original conditional statement, meaning "If [tex]\( p \)[/tex] then [tex]\( q \)[/tex]."

2. Negate both components:
- [tex]\( \sim q \)[/tex] means "not [tex]\( q \)[/tex]."
- [tex]\( \sim p \)[/tex] means "not [tex]\( p \)[/tex]."

3. Reverse the order:
- The parts are swapped.

So, the contrapositive of [tex]\( p \rightarrow q \)[/tex] is [tex]\( \sim q \rightarrow \sim p \)[/tex], which translates to "If not [tex]\( q \)[/tex], then not [tex]\( p \)[/tex]."

Therefore, the correct answer is:
[tex]\[ \boxed{\sim q \rightarrow \sim p} \][/tex]
