Consider a frame of bowling pins shown below, where each represents a pin: There are 5 rows and a total of 15 pins. If we had only the top 4 rows, then there would be a total of 10 pins. If we had only the top three rows, then there would be a total of six pins. If we had only the top two rows, then there would be a total of three pins. If we had only the top row, then there would be a total of one pin
