Probability = desired outcomes / possible ones

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

True. Thanks for clearing that up.

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

i was kinda asking for % answer.

Approximately .27%
