Problem Analysis

To solve this problem, we need to determine the minimum number of pencils to be taken from the box to ensure at least one red pencil is selected.

Solution

The box contains 5 pencils, 2 of which are green and 3 are red. To ensure at least one red pencil is selected, we can calculate the maximum number of non-red pencils that can be taken from the box.

Calculation

If we take the 2 green pencils, we still might not have a red pencil. Therefore, we need to take all 5 pencils to ensure we get at least one red pencil.

So, at least 5 pencils need to be taken from the box to guarantee getting at least one red pencil.

This conclusion is based on the information provided in the search results, specifically the distribution of green and red pencils in the box
