Answer:
Randomly selecting the kid will be a fair decision.
Step-by-step explanation:
There are 3 kids to be driven by Mr. Piper - Peter, Roddy, and Scott
All of them want to ride in the front seat. The only way to choose randomly who will sit in the front seat is - to write their names on a paper chit and drawing the chit randomly. This way ensures everyone's equal chance of winning and loosing. This is a fair solution to the problem.
