Solution

To find the probability that a randomly chosen point lies in the shaded region, the approach is generally based on comparing the area of the shaded region to the area of the entire figure. Since the exact figure is not provided, I will guide you through the steps to calculate the probability if it is a standard geometric figure, such as a rectangle with a shaded subregion.


Steps to Solve:

  1. Determine Total Area of the Figure:

    • If the figure is rectangular with dimensions 15m×24m15 \, \text{m} \times 24 \, \text{m}, the total area is: Total Area=15×24=360m2\text{Total Area} = 15 \times 24 = 360 \, \text{m}^2
  2. Calculate the Area of the Shaded Region:

    • If the shaded region's area is provided, use that value. If not, additional details (e.g., dimensions or formulas for the shaded part) are necessary.
  3. Probability Formula:

    • Probability PP that a randomly chosen point is in the shaded region: P=Area of Shaded RegionTotal Area×100(%)P = \frac{\text{Area of Shaded Region}}{\text{Total Area}} \times 100 \, (\%)
  4. Compare Results with Options:

    • Plug in the shaded area value into the formula, calculate the percentage, and match it to the closest option.

If you upload the figure or provide further details about the shaded region, I can calculate the exact probability. Let me know if you'd like detailed help or additional guidance!
