Since the 6 numbers drawn at every Lotto draw constitute 15 pairs, a given pair of a Lotto game is expected to be drawn once in 57 draws. If we are dealing with more than a few hundreds of draws, then it is unlikely that a pair might not have been drawn at all. Note also that the frequencies of the pairs must demonstrate a nomal distribution. That is, a few pairs with low and high frequencies; a large number of pairs with frequency values in the middle.
