A box of 6 coins (penny, nickel, dime or quarter) worth $0.67 is shaken. What is the probability that a nickel is drawn first and then a quarter? Assume no replacement and that all coins are equally likely.

Answer 23

Well the probability of getting a nickel is 1/6. Then for a quarter it's 2/5 cause there has to be 2 of them in there, to make the problem correct. 1/6*2/5=1/15
