Using it's concept, it is found that the probability that the special ball is chosen is given by:
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
The total number of outcomes is given by the combination of k balls from the set of n balls, given by:
One ball is special, hence the probability the special ball is chosen is given by:

Hey there!
Let's look at our graph here. It is a 4 x 8 chart, which means there are 32 total squares. 12 of these squares are highlighted in black. This gives us 12/32, which is equal to 3/8. Therefore, we can eliminate answer D as an option.
Now, we are looking for a percent of a fraction. Usually when you draw a chart that represents multiplying fractions, the bars will overlap. We do see 5 gray squares, but if that is all, this chart would not really represent anything. Let's say it goes all the way across the top, giving us 8 gray squares, 3 of them also being black.
This means we have 8/32, or 1/4 as our other fraction. As we said before, 3 of these squares are both black and gray. This is 3/32, so the answer to our problem has to be 1/12.
We have fractions 3/8 and 1/4.
Therefore, our answer is H.
I hope this helps!
