Stuck with this problem. Pls help
Robin & Susan are playing a game with 9 cards. The cards are numbered from 1 to 9. Robin & Susan take turns to pick up one card each. They keep all the cards they have picked. The winner is the first person who can make a total of 15 out of the cards in thier hands
Robin starts the game. After 2 turns each, Robin is holding the cards numbered 6 and 4, and Susan is holding cards numbered 2 and 5. It is Robin's turn to pick a card and he picks 8. Who do you think will win the game. Explain your answer carefully
My thoughts
Not sure what the answer is:
Robin could win the game if he can pick a 1 OR Susan can win the game if she picks a 1 and 7 next. So not sure what is the expected answer
Any help or pointing in the right direction greatly appreciated
Many thanks in advance
