Dad bought three kinds of tea, green tea, black tea and Pu 'er tea. There are three different tea boxes at home. How many kinds of tea can you match?

There are six collocation methods:

1, A-green tea, B-black tea, C-Pu 'er tea

2.A-green tea, B-Pu 'er tea and C-black tea.

3.A-black tea, B-green tea and C-Pu 'er tea.

4.A-black tea, B-Pu 'er tea and C-green tea.

5.A-Pu 'er tea, B-black tea and C-green tea.

6.A-Pu 'er tea, B-green tea and C-black tea.

Anyway, there are six answers to this kind of question.

Hope to adopt, thank you! ! !
