Hi,

A. rolling a sum of 11 on two fair six sided dice: P = 2/36 = 1/18

B. drawing a red nine out of a standard 52 card deck given it’s not a face card or an Ace.

P(A|B) = P(A and B)/P(B) = 2/36 = 1/18

C. rolling a sum of 10 on two fair six sided dice: P =  3/36 = 1/12

D. rolling a sum of 7 on two fair six sided dice:  p = 3*36 = 1/6 

E. drawing a six out of a standard 52 card deck given it’s not a face card or an Ace.

P(A|B) = P(A and B)/P(B) = 4/36 = 1/9
