something like this I guess

local item_table = {
    -- {item_id, max_count, chance}
    {1111, 1, 1000},
    {2222, 2, 2500},
    {3333, 3, 7000}
}

local index = math.random(#item_table)
local rand = math.random(100000)
if rand <= item_table[index][3] then
    player:addItem(item_table[index][1], math.random(item_table[index][2]))
end

if rand <= item_table[index][3] then
    player:addItem(item_table[index][1], math.random(item_table[index][2]))
end

it will return 1 item?

Will give 1 random item from the list of items, if the random number chosen is less then or equal to the chance value.

-- Edit

Sorry, I should be more clear.

The script will choose a random item, then compare the random number against the chance value of the random item chosen.
There's no guarantee of an item.
