The centre pages of the Weekly Sentinel consist of a page of film and theatre reviews and a page of classified advertisement. The number of misprints in the reviews can be modelled using a Poisson distribution with mean 2.3 and the number of misprints in the classified section can be modelled by a Poisson distribution with mean 1.7. Using cumulative Poisson probability tables, find

(a) the probability that on the centre pages there will be more than five misprints,

(b) the smallest integer # such that the probability that there are more than # misprints on the centre pages is less than 5%.
