Final answer:
The question seeks to identify a shape with a 35% selection probability, but lacks specific context or data to determine which shape that is. Usually, such a problem would require additional details about the representation of each shape to calculate probabilities.
Step-by-step explanation:
The question at hand is asking about the probability of selecting a certain shape, given the information that there is a 35% chance of selecting that shape. This corresponds to 7 out of 20 selections. However, the specific shapes listed (triangle, square, etc.) and their associated probabilities are not provided in the information you've shared. To answer which shape has a 35% chance of being selected, we would need additional context or data specifying the probability for each shape.
Typically, a problem like this would include a list or a description of how many times each shape is represented in a collection, from which you can calculate the probability of selecting each one. Since this information isn't given, we can't definitively answer the question about which shape corresponds to a 35% selection chance.
