A dart is thrown at the square target shown. Assuming the dart hits the target at a random location, what is the probability that it will be in the shaded region? Express your answer as a common fraction.
Outer square is 4" away from medium square. Medium square to small square is 3". Full small square is 2". Shaded area is between medium and small
I have a little different answer than Melody......see the following pic.....{I'm assuming the small square is 2 inches on each side....I''m also assuming that the distances between the squares are measured from edge to edge}
The area between the medium square and the small square {the shaded area} = 8^2 - 2^2 = 64 - 4 = 60 square units
And the area of the whole dartboard = 16^2 = 256
So....the probability that the dart lands in the shaded area between the small and medium square = 60/256 = 15/64
hi Mellie,
since when is a dart board square?
Anyway the area of the whole board is 4*4=16 cm squared. That will be the denominator.
the shaded area will be 3*3-2*2 = 9-4 = 5 cm squared.
So the prob that it will be in the sahaded region is $${\frac{{\mathtt{5}}}{{\mathtt{16}}}}$$

Actually, Melody was correct, but still thank you so much for helping me!!
$$The total area of the dartboard is $4\times4=16$ square inches. The area of the shaded region is the area of the $3\times3$ region after subtracting the area of the $2\times2$ region, or $9-4=5$ square inches. The shaded region is $5$ square inches out of the possible $16$ square inches the dart could hit, so the probability of the dart hitting the shaded region is $\boxed{\frac{5}{16}}$.$$
No Mellie,
Chris answered this one correctly mine is not correct.
(Unless perhaps you were given a pic to help eliminate confusion :/ )
Your resorces often seem to give you incorrect answers :)
Or at least they often give you the correct answer to a slightly different question from the one that they actually asked.
