A senator campaigning for reelection is trying to raise $$\$ 100,000$$ for a last-minute series of television advertisements. He thinks there is a $55 \%$ probability he will be able to raise the money and that if he does there is then a $70 \%$ chance he will be reelected. He also feels that if he fails to raise the money then there will still be a $55 \%$ probability he will be reelected. Use a tree diagram to find $P$ (he did not raise the money, given he was reelected).
