I don't think so. Lets look at it.
There are 2^3=8 things that can happen when you flip three coins.
Two of those HHH,or TTT is heads or tails.
so in 8 tries, one expects 2 heads/tails.
So in 8 trials, six are not heats or tails.
6:2 is the odds, and geepers, you are exactly right. Go to the head of the class.
What are the odds against getting all heads or all tails in three successive flips of a coin?
I say it is 3:1, is this right?
