What is the probability that it will land inside the circle with diameter 2 m?
A) \[\frac{\pi }{8}\]
B) \[\frac{\pi }{28}\]
C) \[\frac{1}{12}\]
D) \[\frac{1}{18}\]
Correct Answer: B
Solution :
\[n(S)=\]Area of rectangle \[=\text{7}\times \text{4}=\text{28 }{{\text{m}}^{\text{2}}}\] \[n(A)=\]Area of circle\[=\pi {{r}^{2}}=\pi {{(1)}^{2}}=\pi \] \[\therefore \]Probability\[=\frac{n(A)}{n(S)}=\frac{\pi }{28}\]
