In a piggy bank, 40% of the coins are dimes and three-eighths of the remainder are nickels. a coin is randomly drawn from the bank. what is the probability that the coin is not a nickel? give your answer as a percent.

In a piggy bank, 40% of the coins are dimes.
3/8 of the remainder are nickels.
The remainder is going to be 60%
1/8 of 60% is 7.5%. (just dividing by 8)
3/8 of 60% = 7.5% × 3 = 22.5% are nickels.
If 22.5% are nickels, then 77.5% are not.
The percentage of coins that aren't nickels is the same as the probability of drawing one because each coin has equal probability to be chosen.

It will might be false
