This is just wrong, and repeating it won't help. 1/1 is 100%. 1:1 is 50%.
Odds (using the X:Y notation) are a ratio of successes to failures,
probability (using the X/Z notation) is a ratio of successes to trials.
In this message, take X to be the number of successes, Y to be the number of
failures, and Z = X+Y, the number of trials. X:Y and X/Z are normal ways to
describe this. X:Z is not.
1:1 means one success to one failure. This is 1/2, or 50%. One success in
two trials.

That's 1:0 or 1/1.
You seem to know the difference between odds and chances, is this just a
terminology hangup? Do you think the X:Z is common usage somehow?
