Solution
The correct options are A Blue is the favourite colour of most students. C Orange is the second most popular colour. From the graph, it can be observed that: Frequency of Blue = 6 Frequency of Orange=5 Frequency of Yellow=3 Frequency of Pink=3 Frequency of Red=2 Frequency of Green=1
Therefore, blue is most favoured colour and orange is second most favoured colour. Thus, options A and C are correct. The least favoured colour is green so option B is incorrect. Also the frequency of green and pink are different. So option D is also incorrect.
