Question
Consider an auto insurance portfolio where the number of accidents follows a Poisson distribution
with parameter λ= 1000. Suppose the damage sizes for separate accidents are i.i.d. (independent
identically distributed) r.v.'s having an exponential distribution with a mean of $2500.
Each policy involves a deductible of $500. Let N₁ be the number of accidents that result in claims,
and N₂ be the number of accidents that do not result in claims.
Answer the following questions 1-5.

Q2
Depends on a situation,
No
Yes
What is the name of the distributions of N₁, №₂?
