Now I don't know how many variations there are to cell phone numbers, but assuming its 20,
1/1000 x 1/20 = 1/20,000

Think your numbers are little off and that doesn't even consider the probability of the intended receiver being in the same school as the actual recipient who also happens to be a teacher /mind boggles
