Answer:

D

Step-by-step explanation:

There are 7 coins total and 4 of them are nickels

if I take a coin out the probability that it WONT be a nickel is 3/7 or 0.57 because the total amount of coins is always the bottom number and 7- those 4 nickels would be 3. So therefore the answer would be D.
