Vladimir and Alphonso Are Collectors of Toy Story Figurines

Vladimir and Alphonso are collectors of Toy Story figurines. Each has six dollar bills to spend on three figurines-Sheriff Woody, Buzz Lightyear, and Jessie-that are put up for auction where Vlad and Alph are the only bidders. They simultaneously and independently write down their bids, in whole numbers adding up to $6, for the three figurines and give them to the auctioneer. Whoever wrote the higher number for a figurine wins it. For example, if Vlad bids ($3, $1, $2) , meaning $3 for Sheriff Woody, $1 for Buzz Lightyear, and $2 for Jessie, and Alph bids ($2, $3, $1) , then Vlad wins Sheriff Woody and Jessie, while Alph wins Buzz Lightyear. If there is a tie, then a fair coin is flipped to determine the winner so that each bidder has 50 percent chance of winning a figurine. Vlad and Alph consider this case as ʺwinningʺ a (1/2) figurine. Vlad and Alph care only about how many more, or less, figurines they win compared to the other.
