The Manager of Mining Company believes that total profit of the firm next year can be modelled using a normal distribution. If the mean profit is \$1,250,000 and a standard deviation is \$250,000.

(a) What is the probability that the firm's total profit will exceed \$1,400,000?

(b) What is the probability that the firm's profit will fall to within \$150,000 of the expected level of profit (i.e. mean profit)?

(c) In order to cover fixed costs, the firm's profit must exceed the break-even level of profit of \$1,050,000. What is the probability that profit will exceed this break-even level?

(d) Determine the profit level that has only 15% chance of being exceeded next year.
