Your school has no backbone. They should either kick you out of school or shut the hell up. That's what I'd tell my teacher. Kick me out or don't. But don't accuse me of something I didn't do. He'd fold in a New York minute.
Imagine a whole pack of 52 in a random order in your head. What is the location of the last heart? Now reverse that deck. What is the location of the first heart?
13/52 times the first heart will be the first card. 13/52 times it'll be the last card too.
