Adam, Ben and Charles love the same girl Rose. Rose cannot choose which one to marry. To settle the love rectangle they agree to have a gentleman "Trual". It is a three way dual. They will stand at three corners of an equal side triangle and take turn at shooting the other man one at a time.
Adam is the worst shooter. He hits a target 1 out of 3 shots. Ben is a little better. He will hit the target 1 out of 2 shots. Charles is the best shooter. He will hit the target every time.
To make the trual a little fair. Adam will shoot first. Ben will shoot second. Charles will be last. Then Adan will shoot again if he still alive. Ben will be next and Charles will shoot after Ben until only one man remain. That man will marry.
How would you shoot if you were Adam?
