Higher November 2021 Unit 2 Q2
2. A company has two sites.
One is in North Wales and the other is in South Wales.
The pie charts below show the distribution of its 96 part-time staff and its 150 full-time staff.
A person is chosen at random from the company’s 246 staff members.
What is the probability that this person works at the site in North Wales? [4]
| Scheme | Marks | Comments |
|---|---|---|
| (number of part-time in North Wales =) \(\dfrac{90}{360} \times 96\) OR (number of full-time in North Wales =) \(\dfrac{144}{360} \times 150\) | M1 | Or equivalent Answers may be seen on the diagram. |
| (number of part-time in North Wales =) 24 | A1 | An answer (or sight) of 24 implies M1. |
| (number of full-time in North Wales =) 60 | A1 | An answer (or sight) of 60 implies M1. |
| (Probability from North Wales =) \(\dfrac{84}{246}\) or equivalent ISW | A1 | FT (‘their 24’ + ‘their 60’) /246 provided M1 gained and (‘their 24’ + ‘their 60’) < 246. Penalise incorrect notation −1. e.g. ‘84 in 246’. |
