Ank and Mini play a game of tick-tack-toe. In this game, the players try to get three circles or three crosses in a row (horizontal, vertical, or diagonal).
They follow the following rules:

• A player always tries to win: if a player can place his own symbol (X or O) in a row that already contains two of his own symbols, he will do so.
• A player always tries to avoid that his opponent wins: if a player can place his own symbol (X or O) in a row that already contains two of the symbols of his opponent, he will do so.

Of course, the first rule has precedence over the second rule, because the game can be won in this way.
In the game shown in the below, six moves have been made. Ank plays with crosses (X) and Mini plays with circles (0). However, we do not know who started the game. Can you tell who will win the game?

My friend and I play a game. Each of us starts with two coins, and we take turns tossing a coin. If it comes down heads, we keep it ourself; if tails, we give it to the other.

I always go first, and the game ends when one of us wins by having all four coins. If we play this game 1400 times, what is the expected number of games that I would win?
