What are the odds of 100 hands no PP?

[LockLow34]

Just played in a home tourney. I made it to the 8th level. With each round lasting 20 minutes and 6-10 players at the tables at various times I'm figuring I saw about 100 hands or so. Out of those 100 hands I had 7 hands with 2 broadway cards (AK, AQ, AT, KQ, KQs, KJ, QJ) and 0 pocket pairs.

What are the odds of having this bad run? More specifically, what are the odds of going 100 hands without a single pocket pair?
