It is 3/8 = 0.375
1/16 These are four independent events each with a 1/2 probability. The probability that all four occur (penny and nickels heads and dime and quarter tails) is: 1/2*1/2*1/2*1/2=(1/2)4=1/16.
One coin is a quarter and the other one is a nickel. The quarter is NOT a nickel!
Assuming American coinage, the two coins would be a 25 cent coin and a 5 cent coin. Assuming non-American coins, one is not a 10 cent coin, but the other one is. The other coin being a 20 cent coin.
The one is a quarter and the other one is a nickel
A quarter and a nickel. The quarter is the coin that's not a nickel!
The probability is 0.5
a quarter and a nickel . The quarter is not a nickel!
A nickel is 5 cents, and a quarter is 25 cents. So 5 nickels are equal in value to 1 quarter.
The puzzle actually reads "What two coins equal 30 cents but one of them is not a nickel?"The answer of course is a quarter and a nickel. The quarter is the coin that's not a nickel!
a quarter and a nickel cuz one is not a nickel n one is
