It depends on
1. what the bag contains (all quarters, quarters and dimes, only one quarter, etc.)
2. whether the quarters are indistinguishable.
Assuming the bag contains a mix of coins of different denominations, and there are at least two quarters.
Say there are 10 coins of which 2 are quarters.
The first pick of a quarter would have a probability of 2/10.
Assuming the first pick was a quarter, then the probability of the second pick would be 1/9.
If the first pick was NOT a quarter, then the probability of the second pick would be 2/9.
What do you think about dependence (of the outcome of the second pick with respect to the first)?
dependent or independent
taking a quarter out of a bag and then taking another quarter out of the bag without replacing the first quarter
