Home Insurance $\quad \$ 500,000 \quad$ Normal; $\mu = 7 \% , \sigma = 2 \%$
Auto Insurance $\quad \$ 450,000 \quad$ Triangular, $\min = 2 \% , \max = 6 \%$ ,
$\quad$ $\quad$ $\quad$ $\quad$ $\quad$ $\quad$ $\quad$ $\quad$ $\quad$ $\quad$ most probable $= 4 \%$
Life Insurance $\quad \$ 550,000 \quad$ Uniform, min $= 4 \% , \max = 10 \%$
a.Use Crystal Ball to simulate total revenues for 2006.Run 1000 replications of the model to find the average revenues.
b.What is the probability that 2006 revenues will exceed $1.6 million?
