Solution 1

Part I

Make a prediction first, by looking at the picture.

Area of region 1/Total area = probability of a dart landing in region 1.

Because probability = desired outcome/all possible outcomes.

Area of region 1= 1*1=1 ft2.

Total area =3*3=9ft2.

Area of region 1/Total area =1 ft2/9ft2=1/9=.

Discussion: What does the answer mean? Does this answer seem reasonable?

Part II

Since Region 1 is 1/9 of the total area, region 2 must be 8/9 of the area. So the probability of a dart, thrown at random, landing in region 2 is 8/9 or
