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.
contrapositive
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.
Look at the statement If 9 is an odd number, then 9 is divisible by 2. The first part is true and second part is false so logically the statement is false. The contrapositive is: If 9 is not divisible by 2, then 9 is not an odd number. The first part is true, the second part is false so the statement is true. Now the converse of the contrapositive If 9 is not an odd number, then 9 is not divisible by two. The first part is false and the second part is true so it is false. The original statement is if p then q,the contrapositive is if not q then not p and the converse of that is if not p then not q
