Question

Find the probability that you throw a dart and land in the region labeled G.

Answer 1

1. Check the picture attached. We can calculate the area of the orange region G by dividing it into right triangles with both legs equal to 1.

Area of one triangle is 1/2*1*1=1/2 units square. 
There are 9 in total, so area G = 9/2 units square.

2. The square has side length equal to 10, so the square area is 100 units square.

3. P(landing in G)=Area of G/total area= (9/2)/100=9/200= 0.045
