Intermediate June 2019 Unit 2 Q13
13. A company has 3 sites based in Wales.
One is in Carno, one is in Holyhead and one is in Porth.
The pie charts below show the distribution of its 128 female staff and 72 male staff.
A person is chosen at random from the company’s 200 staff members.
What is the probability that this person works at the Porth site? [4]
| Scheme | Marks | Comments |
|---|---|---|
| (number of females in Porth =) \(\dfrac{90}{360} \times 128\) OR (number of males in Porth =) \(\dfrac{120}{360} \times 72\) | M1 | Or equivalent |
| (number of females in Porth =) 32 | A1 | Answers may be seen on the diagram. An answer of 32 implies M1. |
| (number of males in Porth =) 24 | A1 | An answer of 24 implies M1. |
| (Probability from Porth =) \(\dfrac{56}{200}\) or equivalent ISW | A1 | FT (‘their 32’ + ‘their 24’) /200 provided M1 gained. Penalise incorrect notation −1. e.g. ‘56 in 200’. |
