If item A costs $10, but on sale it's buy 1 get 1 free, so I pay $5 for each, thus 50% off?
Or is 50% off when you just pay $5?
NY Lotto gives you 2 tickets for $1. Their odds are 22.5m for $1; which is 50% off.

However, don't you need to buy 50% to reduce by 1/2?
If 1 out of 10 boxes has $10. Tickets are $1 each. I need to buy 5 tickets($5) to get 50/50 odds of winning; not 2 tickets for $1 correct?
