5 The weights of full cans of a particular brand of pet food may be taken to be normally distributed, with mean 260 g and standard deviation 10 g. The weights of the empty cans may be taken to be normally distributed, with mean 30 g and standard deviation 2 g. Find (i) the mean and standard deviation of the weights of the contents of the cans (ii) the probability that a full can weighs more than 270 g (iii) the probability that two full cans together weigh more than 540 g.
