How would I make a Pandora's Box?

Hi, I am trying to make a pandoras box in roblox but I am stuck at the scripting part I don't know what to do So my question is that if can anyone here help out with the script?. If so that will be greatly appreciated

This would work in a similar way in choosing any card from a deck of cards randomly. You can implement this idea to do different things.

function getRandomCard() 
  local number = math.random(13)
  local suit = math.random(4)
  local card = ""
  if number >= 1 and number <= 9 then card = number + 1
  elseif number == 10 then card = "Jack"
  elseif number == 11 then card = "Queen"
  elseif number == 12 then card = "King"
  elseif number == 13 then card = "Ace"
  else card = "?" end
 
  card = card .. " of "
 
  if suit == 1 then card = card .. "Hearts"
  elseif suit == 2 then card = card .. "Diamonds"
  elseif suit == 3 then card = card .. "Clubs"
  elseif suit == 4 then card = card .. "Spades"
  else card = card .. "?" end
 
  return card
end
