A mortgage company manages 1, 000 mortgages. Mortgages default at a rate of 10 per year (you can assume this rate remains constant and that defaults can be described as a Poisson process). Every defaulted mortgage gives a loss of $100, 000. Every mortgage that doesn’t default gives a yearly profit of $1, 000. Let X be the number of mortgages that default in a year and let F be the total earnings in a year. 1) Find the yearly...
