This is how i would do it.................


the chances of the player who has won 2/3 winning.....................if they played it through is 50/50
The chances of the other winning is 25 percent.................

why..?????  coin toss............only two possibilities........heads or tails..............                .5 for any single toss.................50/50 either wins.............but the one player only needs to win one out of two coin tosses..........the other both..............   .5 times .5 is .25.................25 percent........the other has twice the future possibility if they played it through..........so twice the jackpot...........if a 100 dollars....................the 2/3 would get about 66 dollars the other 33.............how?  let x = the share of the lesser possibility..........B...............2x the other............. 2x + x = 100......................3x= 100.............100 divided by 3...........is .333..............
