The probability of drawing a king or a nine from a standard deck of 52 cards is (4 + 4) in 52, or 8 in 52, or 2 in 13, or about 0.1538.
There are four 9's and four jacks. If you can use all of them, you can use 8 out of 52 cards. The probability of drawing one of these cards is therefore 8/52 = 0.1538 or a 15.38 % chance.
...from what? Is is essential to know the properties of the items you are drawing from. If the question applies to a deck of cards (which the wording alludes to), then the probability is 1/13. There are 4 9's in a deck of cards, and there are 52 total cards. 4/52=1/13
It is 2/13.
Use of the word "or" is addition; e.g. probability of drawing out of a standard deck of cards a 9 or a 10 which is 4/52 + 4/52 = 8/52 or 2/13.
The probability of drawing 3 cards, all with the value of 9, from a standard 52 card deck, is ~0.018%.

Let's call the chance of drawing a 9 on the first draw P(A). Since there are four 9s, P(A) is 4/52. Probability of not drawing a 9 is 1-(4/52). Each draw is independent so we multiply the probabilities. The probability of EXACTLY one 9 in two draws if P(A)P(1-A)=12/169 which is a about .071
The probability that a single card, drawn at random, is a 9 is 1/13.
If you draw 9 or fewer cards, the probability is 0. If you draw 10 or more card, the probability is 1.
There are 9 number cards that are Spades (2-10), and there are 52 cards in a deck of cards. Therefore the answer is:9/52 = 0.173
Probability (P)of drawing 5 hearts (H) is: P(H) and P(H) and P(H) and P(H) and P(H). There are 13 hearts in a 52 card deck. So, probability is: 13/52 * 12/51 * 11/50 * 10/49 * 9/48 or 154440/311875200 or 0.000495.
