The ata that can be painted using one litre of Luxibrite paint is normally distributed with mean 13.2 m and standard deviation 0.197 m. The corresponding figures for one of Maxigloss paint are 13.4 m2 and 0.343 m2. It is required to paint an area of 12.9 m. Find which paint gives the greater probability that one litre will be sufficient, and obtain this probability. (C)
