The answer depends on how many are picked,whether they are returned after picking and whether the picking is done at random.
In a single random selection the probability is 17/25.
In a normal deck of cards, it is 1.
There are 8 marbles that aren't black, out of a total of 12 marbles, so the probability is 8/12 or 2/3.
If you mean the probability that independent events will occur, it is the product of the individual probabilities that they occur. Ex: Probability of picking a red marble from a jar with 4 red and 6 green marbles and picking a black card from a deck of 52. P(red) = 4/10 = 2/5 P(black card0 = 26/52 = 1/2 P(both) = 2/5 x 1/2 = 1/5

When you are asked what is the probability of drawing "thing a" when you have only the same amount of "thing b," is called an equally likely event. For example: In a hat you have 8 black marbles and 8 black marbles. Since there the same amount of both, the chance of picking a black marble is 50% and picking a blue marble is 50%. This is an equally likely event.
The probability of picking a black ace in one random draw from a normal pack of playing cards is 1/26.
In a normal deck of cards, it is 1.
The theoretical probability of randomly picking each color marble is the number of color marbles you have for each color, divided by the total number of marbles. For example, the probability of selecting a red marble is 3/20.
There are two black 6's in a deck of cards, the probability of not picking one is 50/52 or 25/26, or 96.2%
2 in 52, or 1 in 26, or about 0.03846.

The drug Yellow Jacket is a type of pill that looks black on one side and black and yellow stripped on the other side. These are sold over the counter as a type of energy supplement.
There are 8 marbles that aren't black, out of a total of 12 marbles, so the probability is 8/12 or 2/3.

The Uganda flag is black, yellow and red horizontal stripped with a white centered crest. It has 6 strips.
0.8.
there is a 50% probability that you will pick a black card out of a full pack of playing cards
