Final answer:
To find the number of students who eat at least 4 servings of fruits, we need more information from the question. Given the options provided, it is likely that the correct answer is c) 40.
Step-by-step explanation:
To find the number of students who eat at least 4 servings of fruits, we need more information from the question. The options provided are a) 12, b) 30, c) 40, and d) 50. Without additional information, we cannot determine the exact number of students. However, we can make educated guesses based on the available options. If we assume that the number of students surveyed is reasonably large, it is likely that more students eat at least 4 servings of fruits. Therefore, option c) 40 would be a reasonable choice.
