There are 3 quarters, 2 dimes, 3 nickels,. 2 coins are drawn one at a time both are dimes. Probability that this may occur is 1/4. Because 2 of the coins are dimes. Is this correct. Please explain

Answer 1

incorrect.
Pr(2dimes)=2/8*1/7=2/56=1/23

In reality, because the coins are very different in size, they are not equal probability to draw out.
