How to write the contrapositive from a conditional statement

The video tutorial explains the concept of conditional statements, specifically focusing on the contrapositive form. It begins with a discussion on the conditional 'P then Q' and transitions into explaining the contrapositive 'not Q then not P'. The teacher uses a practical example involving fishing to illustrate these logical concepts, where 'P' is 'I go fishing' and 'Q' is 'I catch fish'. The contrapositive is demonstrated as 'If I don't catch any fish, then I did not go fishing'.
