How do I randomize functions?

I am trying to call the functions randomly. But I do not know where to start. Any tips on how to begin? I have tried using math.random but no success.

local paper = game.ReplicatedStorage.Spawnables.Paper
local folder = game.ReplicatedStorage.Spawnables

-- paper spawnings
	function paperSpawn()
	local spawnPaper = paper:Clone()
	spawnPaper.Parent = workspace
	local xpos = math.random(-100, 100)
	local ypos = 0.5
	local zpos = math.random(-100, 100)
	spawnPaper.Position = Vector3.new(xpos, ypos, zpos)
	end
	function voidSpawn()
	local spawnPaper = folder.VoidPaper:Clone()
	spawnPaper.Parent = workspace
	local xpos = math.random(-100, 100)
	local ypos = 0.5
	local zpos = math.random(-100, 100)
	spawnPaper.Position = Vector3.new(xpos, ypos, zpos)
	end
	function redPaper()
	local spawnPaper = folder.RedPaper:Clone()
	spawnPaper.Parent = workspace
	local xpos = math.random(-100, 100)
	local ypos = 0.5
	local zpos = math.random(-100, 100)
	spawnPaper.Position = Vector3.new(xpos, ypos, zpos)
	end
	function LightPaper()
	local spawnPaper = folder.LightPaper:Clone()
	spawnPaper.Parent = workspace
	local xpos = math.random(-100, 100)
	local ypos = 0.5
	local zpos = math.random(-100, 100)
	spawnPaper.Position = Vector3.new(xpos, ypos, zpos)
	end
	function GoldPaper()
	local spawnPaper = folder.GoldPaper:Clone()
	spawnPaper.Parent = workspace
	local xpos = math.random(-100, 100)
	local ypos = 0.5
	local zpos = math.random(-100, 100)
	spawnPaper.Position = Vector3.new(xpos, ypos, zpos)
	end
	function DiamondPaper()
	local spawnPaper = folder.DiamondPaper:Clone()
	spawnPaper.Parent = workspace
	local xpos = math.random(-100, 100)
	local ypos = 0.5
	local zpos = math.random(-100, 100)
	spawnPaper.Position = Vector3.new(xpos, ypos, zpos)
	end
	function EmeraldPaper()
	local spawnPaper = folder.EmeraldPaper:Clone()
	spawnPaper.Parent = workspace
	local xpos = math.random(-100, 100)
	local ypos = 0.5
	local zpos = math.random(-100, 100)
	spawnPaper.Position = Vector3.new(xpos, ypos, zpos)
	end
	function PurplePaper()
	local spawnPaper = folder.PurplePaper:Clone()
	spawnPaper.Parent = workspace
	local xpos = math.random(-100, 100)
	local ypos = 0.5
	local zpos = math.random(-100, 100)
	spawnPaper.Position = Vector3.new(xpos, ypos, zpos)
	end
