I NEED THE ST DEV OF BITH!!! Consider two local banks. Bank A has $80$ loans outstanding, each for $$1\mathrm{.}3$ million, that it expects will be repaid today Each loan has a $4\%$ probability of default, in which case the bank is not repaid anything. The chance of default is independent across all the loans. Bank B has only one loan of $$104$ million outstanding, which it also expects will be repaid today It also has a $4\%$ 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

a$.$ The expected overall payoff of each bank.

The expected overall payoff of Bank A Is $$,$ million. $($Round to two decimal places$)$
