IT IS A the question is trying to trick you by including quarters, nickels, etc. If you take 1 of these for example a quarter you only 2 sides, tails & heads that means you have a 50/50 chance if you flip it or 1/2. If you don't get this I will explain it a little more, you have a 3d object, the quarter however it is flat so if you flip it it will land on side A or side B, but there is only Side A and B because it is flat on both sides. Hope you understand.
Pretty much if you flip you only have two chances not 16 like you chose.
