Everyone, guess what I made!

I made a random lottery machine in Minecraft!!! Using a composter, no less 😎😎😎 How it works: Put in seeds, food, etc. ⬇️ Each food item has a different chance of filling up the composter by one slot. ⬇️ If a slot fills up according to the set probability, the lottery is successful; if not, it's a failure. (Meaning, you can manipulate the probability by choosing what food to put in 🔥🔥) Am I the first to do this? Or has someone else already made one? 🤔
