We first find the contrapositive by switching the hypothesis and conclusion and then negating both:
"All people who do not get lots of mail are people who do not win lotteries."
The contrapositive of a true statement is true.
From here we find the converse by switching the hypothesis and conclusion of the newest statement:
"All people who do not win lotteries are people who do not get lots of mail."
This is essentially a negation of the original statement; a negation of a true statement is false.
