A company makes cricket balls and tennis balls. The weights of cricket balls, $$\(C\)$$ grams, follow a normal distribution $$\[ C \sim \mathrm{N}\left(160,1.25^{2}\right) \]$$ Three cricket balls are selected at random. Find the probability that their total weight is more than 475.8 grams. (4) The weights of tennis balls, $$\(T\)$$ grams, follow a normal distribution $$\[ T \sim \mathrm{N}\left(60,2^{2}\right) \]$$ Five tennis balls and two cricket balls are selected at random.
