50 minutes for me , but that is just because I use it so much and therefore increase the probability that I see a long confirmation time. Most confirmations are 7-12 minutes.
It's a Poisson process, with a mean of 10 minutes. So...
What is the probability that the next block will be found within 10 minutes from now?
63.212%
Or within 1 minute?
9.516%
Or 10 seconds?
1.653%
Or 1 second?
0.167%
