Anyways, to get a random player we can just use table[index]. Since the GetPlayers() method returns a table of all the players in the game, this will work. To get the actual random number, we use math.random(), and the # sign to make sure that number is in between 1 and the number of players in the game.

local players = game.Players:GetPlayers()
local randomPlayer = players[math.random(1,#players)]
print(randomPlayer.Name)

To detect when a player dies, we need to use the Died event. To connect this event to all players, we just look through Players with a for loop. Then, since we want to ignore the random player, check if the current player equals the random player, and if it doesn't, connect it to the event.

for i,v in pairs(game.Players:GetPlayers()) do
    if v ~= randomPlayer and v.Character then
        v.Character.Humanoid.Died:connect(function()
            print(v.Name.."died!")
        end)
    end
end
