Foundation June 2017 Unit 1 Q16
16. David, Jane and Mary are beach inspectors.
Three beaches, Harlech, Rhyl and Porthcawl, are all to be inspected on a certain day.
It is decided to share the work so that the inspectors will visit one beach each, chosen at random.
List all the possible different ways they could share the work.
One has been done for you. [2]
David ⟶ Harlech, Jane ⟶ Rhyl and Mary ⟶ Porthcawl
Corrected by Westie's Workshop
- The board's question paper printed “Porhcawl”. Changed to “Porthcawl” because the beach is Porthcawl, as spelt in the example underneath the question.
Original: see the board's question paper PDF (link above).
