Using it's concept, the probability that the first coin is a nickel and the second coin is a quarter is: 2/39.
What is a probability?
A probability is given by the number of desired outcomes divided by the number of total outcomes.
Hence:
- For the first coin, out of 13 coins, 4 are nickels, hence the probability is 4/13.
- For the second coin, considering that a nickel was taken first, 2 out of 12 coins will be quarters, hence the probability is 2/12 = 1/6.
Then the probability for both coins is:
p = 4/13 x 1/6 = 4/78 = 2/39
