Answer:5/6

Explanation:

Each Coin has two possible outcomes heads or tails

if there are 3 coins and two outcomes for each coin you multiply 3 and 2 and that is a total of 6 possible outcomes

Since the question is saying it can't have more than 2 heads we subtract what we don't want with the total possible outcomes

Out of the 6 outcomes how many are there where all of the coins land on heads? Only 1

6-1=5

Out of 6 outcomes 5 of them the coins landed on 2 heads or less

5/6

Suppose that the required reserve ratio is 20%. If Saanvi deposits $4,000 in cash in her checking account, and her bank lends $1
Oksi-84 [34.3K]

The fact that Saanvl deposits the $4,000, means that initially, the money supply remains the same.

<h3>What happened to the money supply after Saanvl's deposit?</h3>

After Saanvl deposited, the money was simply converted from cash to cash deposits at the bank.

Both of these things are considered to be a part of money supply so there is no change in money supply initially.
