    Probability = desired outcomes / possible ones

    You are asking on one day out of 365, so I would say \frac{1}{365}

    Just a note: this only holds if the outcomes are equally probable.

    It's just a small detail but a very important one.

    For example, it's true for a (perfect) dice: chance on throwing 6 is desired/possible = 1/6.

    But let's take the lottery: chance on winning? Possible outcomes: yes and no, so 2. Chance: 1/2. I hope so, but I don't think so
