How do use Math.Random help?

I'm trying to make the Script change the name of a Part to one of the randomly selective name in the Table.

myTable = {"Bob","Mike" ,"Jack"}--Here my table
part = script.Parent

while true do 
	wait(1)
part.Name = myTable[math.random(1,#myTable)]--Here where I want my part name to change to random name of the table.
end

I just started to learn Scripting and I'm currently playing around with Math.random but I'm having some trouble on how to use Math.Random. All answer are appreciated! :)
