Find ${\text{P}}(A \cap B)$.

Find ${\text{P}}(A \cup B)$.

On the following Venn diagram, shade the region that represents $A \cap B'$.

Find ${\text{P}}(A \cap B')$.

correct substitution     (A1)

eg     $0.3 \times 0.6$

${\text{P}}(A \cap B) = 0.18$     A1     N2

correct substitution     (A1)

eg   ${\text{P}}(A \cup B) = 0.3 + 0.6 - 0.18$

${\text{P}}(A \cup B) = 0.72$     A1     N2

     A1     N1

appropriate approach     (M1)

eg     $0.3 - 0.18,{\text{ P}}(A) \times {\text{P}}(B')$

${\text{P}}(A \cap B') = 0.12$   (may be seen in Venn diagram)     A1     N2
