A market stall sells vegetables. Two of the vegetables sold are broccoli heads and cabbages. The weights of these broccoli heads, $$\(B\)$$ kilograms, follow a normal distribution $$\[ B \sim \mathrm{N}\left(0.588,0.084^{2}\right) \]$$ The weights of these cabbages, $$\(C\)$$ kilograms, follow a normal distribution $$\[ C \sim \mathrm{N}\left(0.908,0.039^{2}\right) \]$$ Find the probability that she pays more than $$\(£ 7\)$$ (4) The market stall offers a discount for buying 5 or more broccoli heads. The price with the discount is $$\(£ w\)$$ per $$\(\mathrm{kg}\)$$. Let $$\(£ D\)$$ be the price with the discount of 5 broccoli heads.
