1 The numbers from 1 to 14 are shown in the Venn diagram.
(a) List the members of the set \(A \cap B\) (1)
(b) List the members of the set \(B'\) (1)
A number is picked at random from the numbers in the Venn diagram.
(c) Find the probability that this number is in set \(A\) but is not in set \(B\). (2)

| M1 | |
Correct answer scores full marks (unless from obvious incorrect working) Answer: \(\dfrac{3}{14}\) | A1 |
| (2) | |
| (4 marks) |
Notes
M1: for \(\dfrac{a}{14}\) with \(a \lt 14\) or
\(\dfrac{3}{b}\) with \(b \gt 3\) or
for 3 and 14 used with incorrect notation e.g. 3 : 14
A1: for \(\dfrac{3}{14}\) oe or 0.214(…)
