A dart is thrown at random at each of the dartboards below.

(I will try to upload the pictures later.  You should have them on your worksheet.)

a.  For each dartboard, what is the probability that a dart will land in a region marked A?  A region marked B?  A region marked C?

b.  For board 1, what is the probability that a dart will land in a region marked A or B?

c.  For board 2, what is the probability that a dart will not land in region C?

Same rules as number 3.
