Imagine a divide the dollar game in which John and Jane are…

Imаgine а divide the dоllаr game in which Jоhn and Jane are trying tо reach a settlement to share $100.  They get one opportunity (that consists of a single proposal by one of them and either acceptance or rejection of that proposal by the other) to reach such a deal.  If they fail to reach a deal, the $100 disappears.  They initially flip a coin to determine who will make the first offer.  If it lands on heads, John can choose to make the first proposal or allow Jane to make the first proposal.  If it lands on tails, Jane can choose to make the first proposal or allow John to make the first proposal.  Which of the following is the most likely equilibrium outcome of this interaction if the coin flip lands on heads and both players are trying to maximize their income?
