[The narrator reads out the onscreen text.]

NARRATOR: Question one. 80 students were asked if they had an MP3 player, a DVD player or both. The information is presented in the two-way table below.

[The two rows of the table are labelled "DVD player" and "No DVD player". The two columns of the table are labelled "MP3 player", and "No MP3 player". Figures in the table show that 36 students have a DVD player and an MP3 player, 12 students have a DVD player but no MP3 player, 6 students have an MP3 player but no DVD player and 26 students have no DVD player or MP3 player.]

NARRATOR: The four regions in the Venn diagram correspond to the four cells in the two-way table.

[The Venn diagram consists of a rectangle containing a blue circle labelled 'DVD' and a yellow circle labelled 'MP3'. The two circles overlap to form a small green area.]

NARRATOR: The two-way table tells us that 36 people owned both a DVD player and an MP3 player. The corresponding region in the Venn diagram is the overlap between both the DVD circle and the MP3 circle. We can place those 36 people in this region.

[The number 36 is written in the green area.]

NARRATOR: The two-way table also tells us that there are 12 people that own a DVD player but don't own an MP3 player. In the Venn diagram, this region is the region within the DVD circle but not overlapping with the MP3 circle. There are 12 people in this region.

[The number 12 is written in the blue area of the DVD circle.]

NARRATOR: The two-way table tells us that there are six people who own an MP3 player but don't own a DVD player. This region corresponds with the region in the Venn diagram within the MP3 circle but not overlapping with the DVD circle. There are 6 people in this region.

[The number 6 is written in the yellow area of the MP3 circle.]

NARRATOR: And lastly, the two-way table tells us that there are 26 people who own neither an MP3 player nor a DVD player. In the Venn diagram, this corresponds with the region outside both the DVD circles and the MP3 circles. There are 26 people in this region.

[The number 26 is written outside the two circles.]

NARRATOR: The Venn diagram is now complete.
