A standard deck of cards has 52 cards. There is only one ace of spades so it is 152 unless u dont want the jokers then its 150 DUH!!!!!!!!!!  Im in 5th grade and i know that!!!!!!!!!!!!

The total number of cards in a deck of cards is 52. There are thirteen cards of spade and four cards of ace. There is only one card which is ace as well as a spade in a deck of 52 cards.

Let A be the event that the a card is selected and it is ace of spade.

P(A)= n(A)/n(S)

P(A)= 1/52
