2⃣ Eliminer le bruit parasite

Alice and Bob play a game of tennis.
Alice serves. Bob receives.
They’re both equally skilled.
So, each point is equally likely to be won by either Alice or Bob — independent of all other points.
What’s the probability that the score is “deuce” at least once during the game?
