...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
If you draw 9 or fewer cards, the probability is 0. If you draw 10 or more card, the probability is 1.
First draw probability of red is 6/10. If first draw is red, then second draw probability of red is 5/9. Multiply the two probabilities to get the overall probability. 6/10 X 5/9 = 30/90 = 1/3
If you draw 40 cards without replacement the probability is 1! If you draw just one, the probability is 1/4.
The probability, if you draw 40 cards, without replacement, is 1. That is, it is a certainty. The probability on a single random draw is 1/4.
The probability of drawing the Ace of Spades on the first draw is 1 in 52. The probability of drawing the Queen of Hearts on the second draw is 1 in 51. The probability of both of those event occurring is 1 in 2652. (1 in 52) times (1 in 51)
Probability of drawing a 7 or 9 is the probability of draw a 7 plus the probability of draw a 9 which is 4/52 + 4/52 = 8/52 = 2/13 = 0.1538.
If you draw 9 or fewer cards, the probability is 0. If you draw 10 or more card, the probability is 1.
First draw probability of red is 6/10. If first draw is red, then second draw probability of red is 5/9. Multiply the two probabilities to get the overall probability. 6/10 X 5/9 = 30/90 = 1/3
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 on a single random draw, from a normal deck of cards, is 1/52.The probability on a single random draw, from a normal deck of cards, is 1/52.The probability on a single random draw, from a normal deck of cards, is 1/52.The probability on a single random draw, from a normal deck of cards, is 1/52.
In the first two draws, the probability is 1/15.
If you draw 40 cards without replacement the probability is 1! If you draw just one, the probability is 1/4.
The probability, if you draw 40 cards, without replacement, is 1. That is, it is a certainty. The probability on a single random draw is 1/4.

To find the probability of choosing two white chips in succession without replacement, we first calculate the probability of selecting a white chip on the first draw. There are 4 white chips out of a total of 10 chips, so the probability of the first draw is 4/10. After removing one white chip, there are 3 white chips left out of a total of 9 chips, making the probability of the second draw 3/9. Therefore, the overall probability of drawing two white chips in succession is (4/10) * (3/9) = 12/90, which simplifies to 2/15.
1 - the chance to draw 2 jacks - the chance to draw no jacks leaves you with the chance to draw just one by elimination. 1 - (1/3)*(1/3) - (2/3)*(2/3) 1 - 1/9 - 4/9 1 - 5/9 4/9
They are independent, because the probability of the first event does not affect the probability of the second event.
