60000km on the ordinary road. Assuming that the durability of this new tyre is approximately normal distributed with a standard deviation of 6000 km, find the probability that a tyre selected at random will last more than 70000km. The tyre manufacturer guarantees to replace the tyres free with the new tyres if they last less than K km, determine the value of K if the tyre manufacturer intends to replace only 1% of all tyres.
