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=.

11% of 50 darts will land in region 1. 50 darts *= 5.5 darts.

88% of 50 darts will land in region 2 50 darts *= 44.5 darts.
 

5.5 darts *10 points per dart = 55 points.

44.5 darts *5 points per dart= 222.5 points.

55 points +222.5 points =277.5 points.
