Today’s Question:
Your friend George gives you the following argument about coin tossing:
The odds of three tossed coins turning up all heads or all tails is one in two, that is 50-50. That is because anytime you toss three coins, at least two must match, either two heads or two tails. So that means the third coin – which is equally likely to be heads or trails, determines the odds.”
