Why does this teleport script only teleport 2 people instead of all players?

When I run the game with 3 players 2 people get tp'd and not everyone. Here is the code.

for i, v in ipairs (game.Players:GetPlayers()) do
local chance = math.random(1,4)
print("starting teleport")

if chance == 1 then
v.Character.HumanoidRootPart.CFrame = CFrame.new(Spawn.Position)


elseif chance == 2 then
v.Character.HumanoidRootPart.CFrame = CFrame.new(Spawn1.Position)


elseif chance == 3 then
v.Character.HumanoidRootPart.CFrame = CFrame.new(Spawn2.Position)


elseif chance == 4 then
v.Character.HumanoidRootPart.CFrame = CFrame.new(Spawn3.Position)
end

The spawn and ghost spawn are just variables for the spawns around the map.

It is supposed to teleport the players in game to spawn 1 2 3 or 4 at random and the randomly chosen player (the ghost) gets teleported to the ghost spawn.

If you can solve this please do.

This may help a little as far as the math portion, it was too big for comments...

--Every time a script in a place uses the math.random function, the random generator generates a random number. However, the random number generator is deterministic. It uses the last random number to generate the next random number. When the scripts starts, the “first” random number is always the same. So every time the script is run, the same random number sequence will be generated.

--When doing something like math.random(1, 100), all the numbers will turn out as whole numbers, which in some cases, just isn’t enough. However, if you did this, then the numbers would be random non-integers between 1 and 100, including decimals.

If you use...

math.randomseed(tick())
for _ = 1, 10 do
	print(math.random(100))
	wait(1)
end

The random numbers should be different every time it runs.
