really? What if it's a definite outcome?
Suppose a box has 6 red balls in it.
If you draw out a ball, what is the probability that is is red?

6/10
where did you get the 10?
There are only six balls. All of them are red!
So, what's the chance of getting a red ball?

The chance of getting a red ball is obviously 6/6 which is 100%!
No offence, but if you cannot get that right, you haven't been paying attention in your lesson book!
Stealing your example here, oobleck.
Probability as a fraction:
number of Favourable outcomes (red balls)
-----------------------------------------
number of Possible outcomes (also red balls)
There are
6 red balls (favourable)
6 red balls (possible)
6/6
No matter what, you get a red ball.
when it is like this, it is definite. It's like 10/10, so the highest possible outcome for any experiment couldn't be 9/10!

Please make sure to reread your lesson carefully, or go to the Khan Academy website and search 'finding probability'.
