27 of the cars are red
10 of the cars are blue
the rest of the cars are white
One of the cars in the car park is chosen at random.
(a) Write down the probability that this car is red. (1)
(b) Find the probability that this car is white. (2)
| Scheme | Marks |
|---|---|
| \(\dfrac{27}{80}\) | B1 |
| (1) |
Notes
B1: oe 0.33(75) or 33(.75)% truncated or rounded
| Scheme | Marks |
|---|---|
80 – (27 + 10) (= 43) oe or 80 – 37 (= 43) \(\dfrac{80 - (27 + 10)}{80}\) oe or \(\dfrac{80 - 37}{80}\) | M1 |
Correct answer scores full marks (unless from obvious incorrect working) Answer: \(\dfrac{43}{80}\) | A1 |
| (2) | |
| (3 marks) |
Notes
A1: oe 0.53(75) or 53(.75)% truncated or rounded
