The number of kilometres travelled on 5 litres of petrol by a particular model of car is defined by the random variable ✗ and follows a normal distribution with mean 52 and standard deviation of 5.3. Express your answers correct to 3 significant figures, without any spaces. (i) Calculate the value associated with P(X > 60). (ii) Calculate the probability that on 5 litres of petrol a car can travel more than 60km. (iii) Calculate the probability that on 5 litres of petrol a car can travel between 60 km and 65 km.
