ANSWER:
Step 1 of 2
A male automobile policyholder will make a claim with probability pm und a female policyholder will make a claim with probability pf, where pfpm.
The fraction of the policyholders that are male is , 0< 1.
If denotes the event that this policyholder will make a claim in the year i.
