The roblox developer website is not good for tables. How can I create a table with a few string texts, then it chooses and prints a random string from the table?

How do I get a random choice from a table?

You can use math.random
Examples:
local table = {"Apple","Orange","String"} -- Items table.
local value = math.random(1,#table) -- Get random number with 1 to length of table.
local picked_value = table[value] -- Pick value from table
print(tostring(picked_value)) -- Print picked value
Pick a random player
local players = {} -- Table
-- Add players to table
for i,v in pairs(game.Players:GetPlayers()) do
table.insert(players,v.Name) -- insert player names to table
end
if players[1] ~= nil then -- Check if table is not nil.
-- Pick random player
local value = math.random(1,#players)
local picked = players[value]
print("I got player " .. tostring(picked))
else
print("Table nil")
end
What does it do? takes a random number from 1 to the maximum length of the table.

Hope it helped :)
local table = {string1, string2, string3} -- make a table
local Chosen = math.Random(0, #table) -- random #
print(table[Chosen]) -- Print it
I apologize for the lack of typing. Im on my phone right now so its very hard. Please leave any questions in the comments.

In Lua array indices start at 1. tab[0] will be nil unless explicitly defined
0
is math.random not math.Random and do not use 0,#table use 1,#table
yHasteeD also used this answer but whatever...
local strings = {"hello", "hello2", "hello3"}
local random_number = math.rando({1, #strings)
local picked_string = strings[random_number]
print(picked_string)
you can also combine strings like this:
print("The chosen string is "..picked_string.."!")
you can also change the variable names and what to print but I guess you already know that...
don't forget to type the previous variables otherwise Roblox won't know what picked_string is
