Math Problem Statement
Consider two local banks. Bank A has
110110
loans outstanding, each for
$1.31.3
million, that it expects will be repaid today. Each loan has a
6 %6%
probability of default, in which case the bank is not repaid anything. The chance of default is independent across all the loans. Bank B has only one loan of
$ 143$143
million outstanding, which it also expects will be repaid today. It also has a
6 %6%
probability of not being repaid. Calculate the following:
a. The expected overall payoff of each bank.
b. The standard deviation of the overall payoff of each bank.
