You can put this solution on YOUR website! A. There are 3 ways to answer the first and each of those ways has 3 ways to answer the second. The answer is 9 ways. (AA,AN,AD,NA,NN,ND,DA,DN,DD)
B. At least one is AA,AN,AD,NA, and DA. None would be 4/9, so everything else (5/9 would be one).
C. Exactly one would be 4/9.
D That is 1/9. (1/3*1/3)
