The Mystery of the Two Envelopes was an interesting topic of probability. The contents were two envelopes, one containing more money and the other containing less money. The amount of money was a whole number, and the amount of money in the two envelopes was different. You can choose an envelope to take the money inside. One strategy is to toss a coin continuously until it appears to be a head. Record the number of times you toss the coin, X, and let X be the number of times you toss the coin plus 1/2. If the amount of money in the first envelope is less than X, then change the envelope. Otherwise, don't change it. After deduction, this strategy can make the probability of getting more money greater than 1/2. There was also a related double-envelope paradox. There were two envelopes containing money, A and B, and it was known that the amount of money in one of them was twice that of the other. After randomly picking an envelope and opening it to get n yuan, some people thought that the expectation value of changing the envelope was 1/2(2n)+1/2(n/2)=1.25n, so it was more cost-effective to exchange it than not to exchange it. However, after exchanging it, they would feel that the original envelope was more advantageous, which led to contradictory logic. In fact, according to another calculation, the chances of winning were the same whether they exchanged or not. For example, if you picked 100 coins and the remaining envelope was 200 coins, you would earn 100 coins. If you picked 200 coins and the remaining envelope was 100 coins, you would lose 100 coins. If you picked 100 coins and the remaining envelope was 50 coins, you would lose 50 coins. If you picked 50 coins and the remaining envelope was 100 coins, you would earn 50 coins. Therefore, the conclusion was the same. There was also the Multiple Envelope Question (with some additional conditions based on the Double Envelope Question): There were two envelopes A and B containing money, and it was known that one of them contained twice the amount of money as the other. After opening any envelope, one could choose to take the money or exchange the envelope. If they decided to exchange, they had to add another envelope C and mix it with the remaining envelope B. They would be used as the candidate envelopes to ensure that the amount of money in envelope C and envelope B was twice that of envelope A and half that of envelope A. If the envelopes were changed continuously, more envelopes would appear.

Years later. "You devil, how many people have you killed? And you still have the face to call yourself a good person? Pah, today I shall act on behalf of heaven to mete out justice."
