In a school, n+100 students have access to three software packages A, B and C. n-1 did not use any software, n-2 used only packages A n-3 used only packages B, n:4 used only packages C n-5 used all three packages n-6 used both A and B. Where n=738 a) Draw a Venn diagram with all sets enumerated as for as possible. Label the two subsets which cannot be enumerated as x and y in any order. b) If twice as many students used package B as package A, write down a pair of simultaneous equations in x and y. c) Solve the equations to find x and y. d) How many students used package C? Put the value of n at the start of the question.
