If a conditional statement is true, then so is its contrapositive. (And if its contrapositive is not true, then the statement is not true).
A conditional statement is true if, and only if, its contrapositive is true.
The contrapositive of the statement "All journalists are pessimists" is "If someone is not a pessimist, then they are not a journalist." This reformulation maintains the same truth value as the original statement, meaning that if the original statement is true, the contrapositive is also true.
It may or may not be true.
by switching the truth values of the hypothesis and conclusion, it is called the contrapositive of the original statement. The contrapositive of a true conditional statement will also be true, while the contrapositive of a false conditional statement will also be false.
If a conditional statement is true then its contra-positive is also true.

A contrapositive means that if a statement is true, than the characteristics also pertains to the other variable as well.

The contrapositive of the statement "If it is raining, then the football team will win" is "If the football team does not win, then it is not raining." This reformulation maintains the same truth value as the original statement, meaning if one is true, the other is also true.
The law of contrapositive states that a conditional statement of the form "If P, then Q" (P → Q) is logically equivalent to its contrapositive, "If not Q, then not P" (¬Q → ¬P). This means that if the original statement is true, the contrapositive must also be true, and vice versa. This principle is widely used in mathematical proofs and logical reasoning to demonstrate the validity of arguments.
