A. A nonface card or a 7 is drawn

For A a nonface card is 10/13 and for a 7 it is 1/13.

Probability is the good / total.
A. How many nonface or 7 cards are there? Divide it by 52. Be careful, a 7 is a nonface card.
B. How many cards are not Kings and not Spades? There are 13 Spades and 4 Kings, but 1 of those Kings is the King of Spades.

A. Ok there are 40 nonface cards and 4 seven cards, what do you mean do I add them and then divide by 52?
B. I think the answer is 4/13, is that right?

A. Are the 4 seven cards included in the 40 nonface cards?
B. correct

A. yes there are 4 seven cards included in the 40 nonface cards, what does that mean do I divide 40 by 52?

Yes, 40/52.
