    we can do the dice first \[P(A)=\frac{3}{36}=\frac{1}{12}\] since you can roll (3,1), (2,2), (1,3)

    \[P(C)=\frac{2}{36}=\frac{1}{18}\] possible rolls are (5,6), (6,5)

    \[P(D)=\frac{6}{36}=\frac{1}{6}\] and that takes care of the dice

    deck has 12 face cards and 4 aces so you know it is not one of those 16 cards and must be one of the remaining 36 cards. there are 2 black sevens, so probability of picking a 7 if you know it is not one of the above 16 cards is \[\frac{2}{36}=\frac{1}{18}\]
