Answer:

Explanation:

According to the bar graph, the frequency of blue is 5, and the frequency of green is 2. To find out how many more students favored blue than green, we subtract the frequency of green from the frequency of blue:

5 (blue) - 2 (green) = 3

Therefore, 3 more students favored blue than green.
