Answer 2

Given: A man is sitting on helicopter which is positioned in such a way that the entire garden is visible to him. The garden is rectangular in shape with a pond of diameter 2 m as shown in the figure, There is a semi-circular concrete patio at one end and two flower beds at the other two corners as shown. The remaining area has beautiful lush green grass. The man drops a ball from the helicopter bed.

To find: The probability that the ball dropped will fall in one of the flower beds.

Solution:

The area of the complete garden forms the measure of the total possible outcomes. The area of the rectangular garden is calculated as follows.

$Area = 8*5$

        $=40 m^{2}$

The two flower beds formed the measure of the favourable number of outcomes. The area of the two flower beds can be calculated as follows.

$Area = 2 * \frac{1}{4} * \pi r^{2}$

         $= 1.57 m^{2}$

Now, the probability of the event can be calculated as follows.

$P(E) = \frac{1.57}{40}$

or

$P(E) = \frac{157}{4000}$

         $= 0.04$

Therefore, the probability that the ball dropped will fall in one of the flower beds is 1.57/40 or 0.04.
