Adam has 4 dimes, 4 quarters and 4 nickels in his pocket. He pulls out 2 coins making sure to put the first one back in his pocket before picking the second. What are the odds that he pulls out 2 nickels?

A. 1/3
B. 1/9
C. 1/16
D. 1/81

prob of 2 nickels = (4/12)(4/12)

= 1/9
so prob of not picking 2 nickels = 8/9

odds in favour of 2 nickels = (1/9) / (8/9)
= 1 : 8

none of the choices are correct for the ODDS
if you wanted the probability of getting 2 nickels it would be 1/9

the odds of an event is NOT the same as the probability of the event.
