Adam and Ben play a game. They pick 6 numbers in turn from 1,2,3,4,5,7,8,9. If a number is picked, it cannot be picked again. If the resulting 6 digit number is a mutiple of 3, then Ben wins; otherwise Adam wins. For example, if the 6 digit number is 123456, then Ben wins; if it is 123458, Adam wins. Determine who has a winning strategy and what it is.(Adam goes first)
