An insurance policy covers $2$ employees of Company Z. The policy will reimburse company Z for a maximum of $1$ loss per employee per year. It reimburses the full amount of the loss up to an annual company-wide maximum of $8000$. The probability of an employee incurring a loss in a year is $40$%. The probability that an employee incurs a loss is independent of the other employee's losses. The amount of each loss is uniformly distributed on $[1000, 5000]$. Given that one of the employees has incurred a loss in excess of $2000$, determine the probability that losses will exceed reimbursements.
So I'm not seeking a solution to this problem. I was able to solve it, but not for the reason stated in the solution. I don't understand what is meant by the following:
$[...]$ The probability that total losses exceed reimbursement $[...]$ is $\frac{1}{6}$ (this pat is not confusing). However, this is conditional on the occurrence of the loss of the employee whose loss is Y (but no longer conditional on the occurrence of the loss for the employee whose loss is $X$, because the event considered is already conditional on $X > 2000$, so the loss has occurred.) $[...]$
The full solution is rather wordy, so I restricted it to the portion that was confusing. (If more of it is needed in order to answer the post, then please let me know.)
