To find the probability that a randomly placed point in trapezoid EFGH is inside circle A, we need to use the area of the trapezoid and the area of the circle.
The probability can be calculated using the formula: \[ \text{Probability} = \frac{\text{Area of Circle}}{\text{Area of Trapezoid}} \]
However, since specific measurements (lengths and dimensions) of trapezoid EFGH and circle A are not provided, we cannot compute the areas directly. Instead, we can consider the provided responses, which suggest potential probabilities.
-
Identify the options: The options given are .76, .95, .05, and .24.
-
Understanding the context: Since circle A is inscribed in trapezoid EFGH, the area of the circle will always be smaller than that of the trapezoid. Hence, the probability cannot be 1 (100%).
Without specific numbers, let's infer the options:
- A probability close to 1 (like .76 and .95) seems too high, as it would imply the circle occupies a significant portion of the trapezoid.
- A very low probability, such as .05, might suggest a very small circle compared to the trapezoid.
Considering reasonable geometric proportions:
- A middle-ground value of .24 would suggest that the area of the circle is a quarter of the trapezoidal area. This proportion could be realistic for certain trapezoidal dimensions.
Based on those considerations, the best estimate with the given options would likely be:
.24
This indicates that about 24% of the area of the trapezoid is taken up by the inscribed circle.
