Randomly Selecting a player as a Seeker?

Im making a game called Squeak! and i want to know how to make a generator that randomly selects a player to be the Human/Seeker?

I'm not sure if that can be consolidated at all, but it should work to the best of my knowledge. Feel free to comment with questions.

local players = game.Players:GetPlayers()
local num= math.random(#players )
local seeker = players[num]

my cousin got this bit of it:

function. selectSeeker()
	return game.Players:getChildren()[math.random(1,game.Players.NumPlayers)]
end
selectSeeker()
