How do you make sure that both signals are powered?

So, I'm making a "map" to try to impress my friends with my redstone and commands, and I wanna make a voting system for a bedwars game. So, I want to make it so that two people have to agree on one mode to prevent complete chaos(there's gonna be three people including me), and I want to make it so that once those two players step on certain pressure plates, it will run a command. If one player steps on a pressure plate of a certain mode, it's not chosen. If no one steps on the pressure plates, the mode isn't chosen either.

You need to create an AND gates.

How it works is that you have 3 levers/inputs all leading up into 3 blocks with redstone torches. Then there will be redstone running into your command block. Im not able to take screenshots right now but will edit the post asap.
