Problem Analysis:
The worksheet is about probability, specifically focusing on determining whether it is "more likely" or "less likely" to grab a specific shape from a set of objects. The task involves analyzing the images provided and making judgments based on the relative frequencies of the shapes.
Step-by-Step Solution:
####
1. First Image: How likely are you to grab a ⬤ (Circle)?
-
Image Description: The image shows a collection of shapes, including circles (⬤) and stars (★).
-
Observation: There are more circles (⬤) than stars (★) in the image.
-
Reasoning: Since there are more circles than stars, it is
more likely to grab a circle.
-
Answer: Tick "more likely."
####
2. Second Image: How likely are you to grab a ▲ (Triangle)?
-
Image Description: The image shows a collection of shapes, including triangles (▲) and squares (■).
-
Observation: There are fewer triangles (▲) than squares (■) in the image.
-
Reasoning: Since there are fewer triangles than squares, it is
less likely to grab a triangle.
-
Answer: Tick "less likely."
####
3. Third Image: How likely are you to grab a ⬛ (Square)?
-
Image Description: The image shows a collection of shapes, including squares (⬛) and stars (★).
-
Observation: There are more squares (⬛) than stars (★) in the image.
-
Reasoning: Since there are more squares than stars, it is
more likely to grab a square.
-
Answer: Tick "more likely."
Final Answers:
1. For the first image (circle ⬤):
more likely
2. For the second image (triangle ▲):
less likely
3. For the third image (square ⬛):
more likely
Explanation:
The key to solving these problems is to compare the relative frequencies of the shapes in each image. If a particular shape appears more frequently, it is more likely to be grabbed. Conversely, if a shape appears less frequently, it is less likely to be grabbed.
Final Answer Box:
\[
\boxed{
\begin{array}{l}
\text{1. more likely} \\
\text{2. less likely} \\
\text{3. more likely}
\end{array}
}
\]
