Question

Eddie believes that if he flips a coin 650 times, it will land heads up exactly 325 times. What would you tell Eddie about his prediction?

Answer 1

325 x 2 is 650. Eddie thinks every other coin flip he does will land on heads, but that prediction can't be verified, therefore his prediction is incorrect.

Answer 2

I would tell Eddie that his prediction isn't wrong, but it could be made better. It isn't likely that the coin will land heads up exactly 325 times. He could say something like "It will land heads up ABOUT 325 times" or "It will land heads up about half the time". The magic word is ABOUT.
