Simple coins (Posted on 2002-04-09) Difficulty: 2 of 5
I toss two coins and look at the outcome. I then tell you that at least one of the coins is showing up as "tails". What is the chance that the other one is showing "tails" as well?

i'm not sure if this is correct, but most of the time, coins turn out 2 b heads when u toss them. so i believe the probability is that the other coin will b heads. i give it a 50-50 chance. i'm not really sure, though. i'm just telling u 2 b exact.
