Player Join Server Error?

So I created a script that was intended to create a part based on whichever random number is picked from math.random. There are no errors from Output.

The problem is that there are not any new parts created when I join the game (through the Roblox Player and through Studio (I'm new to this part of scripting so I don't know if you're character loads before the scripts as if it was single player mode).

Here's the script I have, thanks for any possible help.

Players = game:GetService("Players")

MyPart1 = Instance.new("Part", workspace)
MyPart2 = Instance.new("Part", workspace)
MyPart3 = Instance.new("Part", workspace)

function PlayerJoin(Player)
    math.random(1,3)
        if math.random == 1 then
            print(Player.Name .. "has entered the game")
            print (MyPart1)
            MyPart1.Name = "Example 1"
            MyPart1.BrickColor = BrickColor.new("Bright blue")
            MyPart1.Position = Vector3.new(100,100,100)
            MyPart1.Size = Vector3.new(30,30,30)    
        end
        if math.random == 2 then
            print(Player.Name .. "got TKO'd by JOHN CENA!!!")
            print (MyPart2)
            MyPart2.Name = "Example 2"
            MyPart2.BrickColor = BrickColor.new("Bright blue")
            MyPart2.Position = Vector3.new(200,200,200)
            MyPart2.Size = Vector3.new(50,50,50)    
        end
        if math.random == 3 then
            print(Player.Name .. "is in the WWE Superslam!!!")
            print (MyPart3)
            MyPart3.Name = "Example 3"
            MyPart3.BrickColor = BrickColor.new("Sea green")
            MyPart3.Position = Vector3.new(300,300,300)
            MyPart3.Size = Vector3.new(70,70,70)
        end
end
