Jan 08, 2008 · The possible outcomes of flipping two fair coins with P(H) = P(T) = 1/2 are HH HT TH TT, each with probability 1/4, but HH is ruled out because we know at least one of the coins is tails. So the probability space is reduced to HT TH TT, which yields P(TT) = 1/3.

• Probability Versus Physics. The coin toss is not about probability at all, he says. It is about physics, the coin, and how the “tosser” is actually throwing it. The majority of times, if a coin is heads-up when it is flipped, it will remain heads-up when it lands. Diaconis has even trained himself to flip a coin and make it come up heads 10 ... For the coin, number of outcomes to get heads = 1 Total number of possible outcomes = 2 Thus, we get 1/2 However, if you suspect that the coin may not be fair, you can toss the coin a large number of times and count the number of heads Suppose you flip the coin 100 and get 60 heads, then you know the best estimate to get head is 60/100 = 0.6
• The probability is 11/16=0.6875. There are 2^(4)=16 possible outcomes when you flip a coin four times.
