A) For the bus's first trip, since there are 22 athletes who need to go to the track and field stadium, there are 22 athletes to choose from. Therefore, there are 22 ways to choose the passengers for the bus's first trip.
B) Once the athletes from the first trip have arrived at the track and field stadium, they are no longer available for the second trip. So, for the bus's second trip, there are 22 - 9 = 13 athletes remaining who still need to get to the track and field stadium. Therefore, there are 13 ways to choose the passengers for the bus's second trip.
