**PsyDAG**, Sunday, November 2, 2008 at 1:28amIf you flip a coin 3 times, here are the possible combinations:

HHH

THH

HTH

HHT

HTT

THT

TTH

TTT

Only 3 of the 8 possibilities will have exactly 2 heads.

The odds*against*getting at most 1 tail are the same as getting no tails. You are right with that answer.

I hope this helps. Thanks for asking.
