Okay, this is probably simple to figure out, but I am not so good with math!
Three columns on display. Five items in each column. They select one item from each column. You are correct in your prediction. What are the odds that you are right in your prediction? Thanks!

Assuming five unique items in each column, the are 125 possible outcomes, making the odds 124 to 1.

(emphasis added), the answer would be 1:124 in favor of being correct. Rarely are the odds in favor of a particular outcome quoted; it is much more common to quote the odds against a particular outcome.
