Question 199672
A card is selected from a deck of 52 playing cards. Find the probability of selecting 
a) a seven given the card is a not a face card. (An ace is not a face card.)
There are 4 7s out of 52 cards, so it's 4/52 = 1/13.
I don't know what you mean about it not being a face card.
-----------------
b) a spade given the card is red. 
Zero, since spades are black ??
