The answer depends on drawing a 9 from WHAT!
In a standard 52 card deck, the probability of drawing an ace is 1/13, and the probability of drawing a diamond is 1/4. The probability of drawing both an ace and a diamond is 1/52.Thus the probability of drawing an ace or a diamond is1/13 + 1/4 - 1/52 = 4/13 or about .308.
The probability of drawing a jack is, P(J) = 1/13.The probability of drawing a queen is, P(Q) = 1/13.The probability of drawing a king is, P(K) = 1/13.The probability of drawing a jack or drawing a queen or drawing a king is;P(J or Q or K) = 1/13 + 1/13 + 1/13 = 3/13 = 0.23076923... ≈ 23.1%.

If you're playing with a full deck a 1 out of 52 chance.
Probability of drawing a heart: 1/4 Probability of drawing a club: 1/4 Probability of drawing a heart or a club: 1/4 + 1/4 = 2/4 = 1/2
It is 20/52 or 5/13.
(13*2+2)/52=0.53846
It is 8/52 or 2/13
Probability of not drawing an ace equals one minus the probability of drawing an ace. The probability of drawing an ace is 4/52 or 1/13. So the probability of not drawing an ace on one draw is 1 - 1/13 or 12/13 or 0.9231 (92.31%).
The answer depends on drawing a 9 from WHAT!
The probability of drawing the first face card is 12 in 52. The probability of drawing the second is 11 in 51. The probability of drawing the third is 10 in 50. Thus, the probability of drawing three face cards is (12 in 52) times (11 in 51) times (10 in 50) or (1320 in 132600) or about 0.009955.
In a standard 52 card deck, the probability of drawing an ace is 1/13, and the probability of drawing a diamond is 1/4. The probability of drawing both an ace and a diamond is 1/52.Thus the probability of drawing an ace or a diamond is1/13 + 1/4 - 1/52 = 4/13 or about .308.
For a normal deck of cards, the answer is none.
Probability of drawing a seven of spades, from a 52 card deck, is 1/52.
