Four 9's
In a standard deck of 52 playing cards, there are four nines, one from each suit: hearts, diamonds, clubs, and spades.
There are 4 nines in a 52 card deck so the probability of drawing a nine is 4/52 or 1/13. Which is 7%
Since there are 2 red nines in a 52 card deck, the probability would be 2/52 or 1/26.
The are 52 possible outcomes if you pick a card from a deck of 52.

2 red fours in a 52 card deck.
There is one Jack of Spades in a 52-card deck.
In a standard deck of 52 cards, there are 4 nines. When you pick the first card, the probability of it being a nine is 4 out of 52, or ( \frac{4}{52} ). After removing one nine, there are now 51 cards left, with 3 nines remaining. Thus, the probability of the second card also being a nine is ( \frac{3}{51} ). The overall probability of both cards being nines is ( \frac{4}{52} \times \frac{3}{51} = \frac{12}{2652} ), which simplifies to ( \frac{1}{221} ).
4 in a deck of 52, 2 red, 2 black
If you don't specify the color, there are four of each card. So out of 52 cards there are four nines. Four out of 52 can be simplified into 1/13, which is about 8%.
