The cashier at a certain restaurant noticed that 16% of all customers pay

of payment. Consider randomly selecting the customers.
Use decimal answers accurate to 4 places.
a. Find the chance that a randomly-selected customer uses a form of
payment that is not cash, P (H).
b. Find the chance that all 8 randomly-selected customers use a form
that is not cash, P (all H').
c. Find the chance that at least one of 8 randomly-selected customers
uses cash, P (at least one H).
