The repair costs for boats in a marina have the following characteristics:

Boat type Number of boats Probability that repair is needed Mean of repair cost given a repair Variance of repair cost given a repair
Power boats 100 0.3 300 10,000
Sailboats 300 0.1 1000 400,000
Luxury yachts 50 0.6 5000 2,000,000

At most one repair is required per boat each year. Repair incidence and cost are mutually independent. The marina budgets an amount, [math]Y[/math], equal to the aggregate mean repair costs plus the standard deviation of the aggregate repair costs.

Calculate [math]Y[/math].
