How to Make a 2X chance to teleport a specific player?

Hello. I have another scripting question. So, I have gotten help and managed to make a random player picker, and make that random player chosen teleport on the stage and do whatever for 100 seconds, then teleport back to spawn. However, I want to make a 2X chance to go on stage if that player pays 1000 points. So basically, I made a frame inside of starter GUI, which contains a text button that says, " 2X CHANCE TO GO ON STAGE" and when you press it, it checks if you have 1000 points, and if you do, it takes them away, just like if you payed for it, then I want to make the 2X chance basically give that specific player who payed the 1000 points have a double chance to go on stage. I ALSO HAVE A LEADERSTAT SET UP ALREADY.

Here is the script to get on stage, and after 100 seconds, you get teleported back to spawn:

repeat 
task.wait(12) -- `task.wait` is the "updated" version of `wait` and is more precise
local num = math.random(1, #game.Players:GetChildren())
local player = game.Players:GetChildren()[num]

local hrp = player.Character.HumanoidRootPart
hrp.CFrame = CFrame.new(Vector3.new(11.667, 26.652, 95.261)) -- Teleport to where you wanted
task.wait(100) -- Wait 100 Seconds
    hrp.CFrame = CFrame.new(Vector3.new(-44.595, 23.642, 93.177)) -- Teleport back to spawn
    until false

If you do not understand or have a question about this, please ask so.

Thanks, from Cubispaghettis.
