If you buy a lotterie ticket that has a 1:100000 chances to win you have a 1:1000000 chance. If you buy two tickets, you have 2:1000000 or 1:500000 chance. Why can I eliminate 500.000 tickets with just one more ticket?
What am I conflating here?
Edit: Thank you guys, this was always something I started wondering about.

Saying you’re “eliminating” tickets is wrong. 1:500000 just means, if we were to select 500000 winning tickets then you’d have, on average, one winning ticket. It makes sense since you bought two tickets in a pool of a million.
