# Exam P Practice Problem 49 – Aggregate Claim Costs

Problem 49-A

The aggregate claim amount (in millions) in a year for a block of fire insurance policies is modeled by a random variable $Y=e^X$ where $X$ has a normal distribution with mean 4 and variance 2. What is the expected annual aggregate claim amount? $\displaystyle (A) \ \ \ \ \ \ \ 403.43$ $\displaystyle (B) \ \ \ \ \ \ \ 244.69$ $\displaystyle (C) \ \ \ \ \ \ \ 148.41$ $\displaystyle (D) \ \ \ \ \ \ \ 90.02$ $\displaystyle (E) \ \ \ \ \ \ \ 54.60$ $\text{ }$ $\text{ }$ $\text{ }$ $\text{ }$

Problem 49-B

The aggregate claim amount (in millions) in a year for a block of fire insurance policies is modeled by a random variable $Y=e^X$ where $X$ has a normal distribution with mean 1.15 and variance 1.2. What is the probability that the annual aggregate claim amount will be less than the expected annual aggregate claim amount? $\displaystyle (A) \ \ \ \ \ \ \ 0.5000$ $\displaystyle (B) \ \ \ \ \ \ \ 0.6915$ $\displaystyle (C) \ \ \ \ \ \ \ 0.7088$ $\displaystyle (D) \ \ \ \ \ \ \ 0.8749$ $\displaystyle (E) \ \ \ \ \ \ \ 0.9599$
