Answer: 35 or 50

Step-by-step explanation: This one actually has 2 answers. On the first draw, you are most likely to draw a quarter. On the second draw, you have and equal probability of drawing either a dime or a quarter. That is, if you do not replace the first coin. If you do, the answer is 50 cents.
