From a set of eight marbles, five red and three white, we choose one at random. What are the odds in favor of choosing a red marble?

Damon,
5 red out of eight total
5/8 = .625 probability
HOWEVER you said odds, as in betting odds.
That is not probability but the ratio of success to failure
in this case 5/3
