on generate10randomNumFrom40
  list40 = []
  repeat with i = 1 to 40
    list40.append(i)
  end repeat
  n = 40
  repeat while n > 1
    m = random(n)
    tN = list40[n]
    tM = list40[m]
    list40[n] = tM
    list40[m] = tN
    n = n - 1
  end repeat
  list10 = []
  repeat with i = 1 to 10
    list10[i] = list40[i]
  end repeat
  return list10
end generate10randomNumFrom40

put generate10randomNumFrom40()
-- [29, 9, 32, 2, 1, 5, 23, 31, 21, 35]

put generate10randomNumFrom40()
-- [24, 28, 40, 21, 35, 20, 30, 11, 33, 18]

Sorry because I am boring but I am beginner, can you tell me where I need to put this code and how to integrate this code with my data base of question .

The code above is to obtain 10 random numbers from 1 - 40. I don't know how you structure your database, but say you have 40 questions in a List; you can use the 10 random numbers as index to pick up 10 random questions.
