The number of possibilities that exist for how people could get off the elevator is 140 possibilities

From the question given, we are told that twenty people get into an elevator in a hotel with seven floors.

  • All of them get off at some point

The number of possibilities that exist for how people could get off is expressed as:

  • Number of possibilities = number of people in the elevator × number of floors
  • Number of possibilities = 20 × 7
  • Number of possibilities = 140possibilities

Therefore the number of possibilities that exist for how people could get off the elevator is 140 possibilities.
