A factory manufactures car tyres that have an average lifetime of 45256 kilometers with a standard deviation of 2756 kilometers and the distribution of lifetime of the tyres is normal. Find the probability that tyre’s lifetime is between 42056 km and 48556 km. What is the lifetime in km, that 56 % of tyres exceed?
