A machine produces small rods and large rods. The diameters of small rods are normally distributed withmean 2 cm and standard deviation 0.12 cm. The diameters of large rods are normally distributed with mean2.2 cm and standard deviation 0.15 cm.(i) Find the probability that a randomly chosen small rod has diameter greater than 2.15 cm.(ii) A box contains one small rod and one large rod. Find the probability that at least one of the rods hasdiameter greater than 2.15 cm.
