The joint distribution of claim frequency and claim severity, conditional on the claim frequency being positive, is given below:

Joint distribution
Claim Size
Claim Frequency
100 300 500 1000
1 0.25 0 0.2 0
2 0 0.37 0 0.18

If the probability that the claim frequency is zero is 0.75, determine the variance of the claim frequency.

Let [math]T_1[/math] be the time between a car accident and reporting a claim to the insurance company. Let [math]T_2[/math] be the time between the report of the claim and payment of the claim. The joint density function of [math]T_1[/math] and [math]T_2[/math], [math]f(t_1,t_2)[/math], is constant over the region

[[math]] 0 \lt t_1 \lt 6, \,\, 0 \lt t_2 \lt 6, \,\, t_1 + t_2 \lt 10 [[/math]]

and zero otherwise.

Calculate [math]\operatorname{E}(T_1 + T_2)[/math], the expected time between a car accident and payment of the claim.

A family buys two policies from the same insurance company. Losses under the two policies are independent and have continuous uniform distributions on the interval from 0 to 10. One policy has a deductible of 1 and the other has a deductible of 2. The family experiences exactly one loss under each policy.

Calculate the probability that the total benefit paid to the family does not exceed 5.
