Probability of trips VS Trips

[AkuJoe]

If two players start with pocket pair, it's 1% chance that both will hit set.

Yeah Joey.. Probability of QQ vs KK both flopping a set.

The second question is given that I had pocket Queens, what is the probability that another player at my table would flop a higher set with a pocket pair (when heads up)preflop)
