Nitpick:

If red paid 4 cents to blue's 7 cents, it would be right to bet on red every time.

Nope.

Consider a deck of 10 cards; 7 blue and 3 red. You write down a list of 10 predictions, in order, and the cards are dealt out; for every card that matches the corresponding prediction you get a reward based on the card color.

If you make 10 blue predictions, and blue cards are worth 7 points, you get 7 correct answers and 49 points.

If you make 10 red predictions, you get 3 correct answers, and red cards have to be worth 16.33 for you to break even.

Fixed. I meant to add a cent to red after making it fair, but accidentally set it up such that the .7 chance one got the seven cents rather than the three in the fair case.
