I find it easiest to work these problems by rewriting the odds as probabilities.

The probability of winning is 3/4. Similarly, the probability of not losing is 5/6, and the probability of not tying is 7/8.

But the probability of tying should be the probability of not losing minus the probability of winning, which we find is:

,

whence the probability of not tying is 11/12. So you would conclude that these odds do not make sense.
