A market stall sells vegetables. Two of the vegetables sold are broccoli heads and cabbages. The weights of these broccoli heads, $$\(B\)$$ kilograms, follow a normal distribution $$\[ B \sim \mathrm{N}\left(0.588,0.084^{2}\right) \]$$ The weights of these cabbages, $$\(C\)$$ kilograms, follow a normal distribution $$\[ C \sim \mathrm{N}\left(0.908,0.039^{2}\right) \]$$ Find, in terms of $$\(w\)$$, the mean and standard deviation of $$\(D\)$$ (2) Given that $$\(\mathrm{P}(D< 6)< 0.1\)$$
