A teacher is planning a theme day for the 500 pupils at their school. The teacher asks a sample of 20 pupils from year 8 which theme they would prefer.
The results are shown in the table.
| Theme | Number of pupils |
| Sport | 7 |
| Art and design | 3 |
| Recipes | 2 |
| Music and movies | 8 |

Riley has a set of cards. Each card has a triangle or circle drawn on it and is coloured red or blue.
The table gives some information about the number of each type of card.
| Number of cards with a triangle | Number of cards with a circle | |
| Number of blue cards | 3 | 8 |
| Number of red cards | 9 | 2 |
