Answer:
(a) Trace the effect of this change through three banks- First National, Second Federal, and Third State.
Antonia deposits $2,000 in First National Bank.
Then First national Bank lends $1,600 to client X that uses the money to purchase something. The seller of that something deposits the money In Second Federal Bank.
Second Federal Bank then lends $1,280 to client Y that decides to use that money to pay his rent. Client Y's landlord then deposits the money in Third State Bank.
Third State Bank will then lend $1,024 to client Z...
(b) How much money will be generated in this banking system?
total money generated in the banking system = Antonia's deposit x money multiplier
money multiplier = 1 / required reserve rate = 1 / 0.2 = 5
so the total money generated = $2,000 x 5 = $10,000
Answer:



I used the relative frequency method
Explanation:
To solve this question we can use the relative frequency to find out each probability. The relative frequency is the ratio of the occurrence of each event and the total number of outcomes.
Here the experiment has been repeated 50 times, so that is the total number of outcomes and the denominator. There are 3 possible events E1, E2, and E3, so we can calculate the ratios to get the probabilities
Event E1 occurred 20 times of the 50: 
Event E2 occurred 13 times of the 50: 
Event E3 occurred 17 times of the 50:
