problem_activity: A huge ping-pong tournament is held in Beijing with 65,536 participants at the start of the tournament. Each round of the tournament eliminates half the participants.
If
$${p(r)}$$
represents the number of participants remaining after
$$r$$
rounds of play, write a function to model the number of participants remaining.
Use your model to determine how many participants remain after 10 rounds of play.
