The probability that point will lies in blue region is 39 %.
Option B is correct.
Probability :
The area of the blue region is computed as,
Area[tex]=\frac{1}{4} *3.14*100=78.5[/tex]
The area of rectangle is computed as;
Area = length * width
Area = 20 * 10 = 200
When a point is randomly selected from the rectangular area of the graph, then the probability that it will be in the blue region,
[tex]P(E)=\frac{78.5}{200} \\\\P(E)=0.3925\\P(E)=0.3925*100=39.25\%[/tex]
Hence, the probability that point will lies in blue region is 39 %.
