Sounds like the tags dice, poker and coin just fall under probability (or I guess 'permutations' or 'combinations'). I recall we got rid of coin some years ago.
eg this Expected Value : Poker
I think dice and poker should be done away with for same reason as coin.
Edit 1: Unless there's for example some graph theory or game theory use for those or something. Maybe poker I get. Same with chess. But why is dice ok while coin isn't?
Edit 2: Martin Sleziak linked this User adding irrelevant tags in comments below. I think the user was me. Lol.
