Ida asked the members of her class how many times they had visited the cinema in the past month. She collected the following data.

$$\begin{matrix} \text{Number of times visited} & \text{1} & \text{2} & \text{3} & \text{4} & \text{8} & \text{12}\\ \text{Number of students} & \text{4} & \text{7} & \text{4} & \text{3} & \text{1} & \text{1}\\ \end{matrix}$$

Draw a bar chart, a pie chart and a pictogram to represent the data.

Refer to a die that is loaded so that the numbers 2, 4 and 6 are equally likely to appear and 1, 3, and 5 are equally likely to appear, but 1 is three times as likely as 2 is to appear. One die is rolled. Assign probability to the outcomes that accurately model the likelihood of the various numbers to appear.
