How to get an exact random number between 2 options (SOLVED)

Questions
1

When I use math.random(10, 20) I get a number between 10 and 20. I want only 2 options. Either 10 or 20. Nothing in between.

You could create a table with the numbers you’d like to choose from (this method is quite scalable if you decide to add more values in the future), and then pick a random value using the indices.

local options = {10, 20}
local choice = options[math.random(1, #options)]

print(choice)

local number = (math.random(1, 2) == 1) and 10 or 20
