We build this fraction using two simple numbers. On top, we place our favorable outcomes—the specific results we are hoping to see. On the bottom, we divide by the total possible outcomes—every single thing that could happen. Let's look at how this looks visually.

So, if there is exactly one winning ticket out of four total tickets in our pool, the math is straightforward. The probability of picking that winning ticket is one over four, which is a twenty-five percent chance.
