There are six sides you could have gotten in the first flip, four of which are heads. Since you have heads, and two of the four heads are on the trick coin, there’s a 50% chance you got the trick coin. If it’s a trick coin, there’s 100% odds of getting heads again, and if it’s not, there’s 50% odds of getting heads again. Since each scenario is equally likely, we average them and get 75% odds of heads on the second flip.” A third added, “5/6. 2/3 of the time it will be from the all-heads coin, and 1/3 of the time you will still have a 50% chance of getting heads.” Watch an interesting conversation with Indian politician & former Union Miner of State, Milind Deora.
