So the difference between the contrapositive and the negation of a claim is that contrapositive reverses and negates to be logically equal to original. Negation of a claim means creating a contradictory statement.

Example : if it rains the ground is wet

R--> G

contrapositive: if the ground is not wet, it did not rain

/G-->/R

negation: it rains but the ground is not wet

R and /G

is this correct reasoning?
