Laura looked at the Professor and was in shock. "Professor I've been told it's naughty to bet before you are 18." Laura was never allowed in the betting shop when her Grandad went in, so seriously why did the Professor want her to bet, well she'd give this a go. "Professor I bet you all my candy for a month that the black one wins." Laura just thought that sounded more interesting than betting tokens, though she handed over two tokens.
