Is this correct? If one card is drawn from a regular deck of cards,what is the probability the card will not be an ace? 1/13 is the probability

The probability it WILL be an ace = 1/13. The probability it will NOT be an ace = 1  1/13 = ?

No, 1/13 is not correct. There is a 12/13 probability that the drawn card is NOT an ace.
