The heights of books in a library, in cm, have a normal distribution with mean 21.7 and standard deviation 6.5. A book with a height of more than 29 cm is classified as ‘large’.

(i) Find the probability that, of 8 books chosen at random, fewer than 2 books are classified as large.

(ii) n books are chosen at random. The probability of there being at least 1 large book is more than 0.98. Find the least possible value of n.
