CSEC Mathematics · May/June 2013 · Paper 2 · Question 3(a)(i)

A survey of 30 students in Form 5 showed that some students used cameras (C) or mobile phones (M) to take photographs. 20 students used mobile phones, 4x students used ONLY cameras, x students used BOTH mobile phones and cameras, and 2 students did not use either cameras or phones.

Copy the Venn diagram below and complete it to show, in terms of x, the number of students in each region.

The mark scheme is shown once you've answered.
