  1. Nice reply! ,,, even if it is a mouthful!
  2. Yes, I would take the bet ... but I do not have a strong proof
  3. I guess it helps if you read the OP correctly! DUH
  4. Actually, that's not quite true as 1 is also a positive integer divisor. Composite really just means "not prime". Thanks
  5. Not familiar with the term in this usage - What do you mean by composite??
  6. Question The OP implies that the unfair coin in your example goes to one side 2 out of 3 time. Can you choose the coing such that you get a specific degree of "unfairness" [e.g., Heads 3 out of 5 times]?
  7. Following the earlier post, let's look at both parts of the equation
  8. Thanks Rainman! I was getting frustrated playing with that grid.
  9. You are right, I thought about it some more [even before I saw your post]
  10. Sorry for the delay. I was out of touch over the holidays.
