First, there are 3 greens out of 8, then 4 blues out of 7. So the probability is these two ratios multiplied:
P(green, blue) = P(green/8) * P(blue/7) = (3/8) * (4/7) = 12/56 or 3/14

What is the probability of selecting 4 red or 5blue marbles?
The probability of selecting 4 red marbles or 5 blue marbles depends on how many marbles there are altogether, and how many of the total number of marbles are red and how many are blue.
A bag contains 16 red marbles and 10 blue marbles If two marbles are chosen at random what is the probability of getting two red marbles?
The probability is 0.3692
When a jar contains 5 white marbles 3 blue marbles and 2 green marbles and if one marble is drawn at random then what is the probability that it will be blue?
There is a probability of 3 that it will be blue.
In a bag there are 3 red marbles and B blue marbles. Two marbles are randomly selected from the bag without replacement. The probability that the two marbles are the same color is 0.5. What is the sum?

What is the probability of pulling a red marbles out of a bag containing 16 red marbles 10 green marbles 14 blue marbles and 10 yellow marbles?
If you pull 35 marbles without replacement, the answer is 1: the event is a certainty. If you pull only one marble, at random, the probability is 16/50 = 8/25.
What is the probability of selecting 4 red or 5blue marbles?
The probability of selecting 4 red marbles or 5 blue marbles depends on how many marbles there are altogether, and how many of the total number of marbles are red and how many are blue.
A jar contains three colored marbles 10 red 15 green and 25 blue If you were to choose without looking what is the probability of selecting a blue marble?
25/50 gives the probability of selecting a blue marble
A bag contains 3 red marbles 5 blue marbles 8 yellow marbles and 4 black marbles what is the theoretical probability of randomly picking each color marble?
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.
A bag contains 4red marbles 2 white marbles a marble is selected kept out the bag and then another marble is selected what is the probability of selecting a red marble and then white marble?
2/6
A bag contains 16 red marbles and 10 blue marbles If two marbles are chosen at random what is the probability of getting two red marbles?
The probability is 0.3692
If a box contains 4 red marbles seven white and 5 blue and two marbles are drawn one at a time with replacement What is the probability that both marbles are white?
Since the box contains 16 marbles, seven of them white, then the probability of drawing one white marble is 7/16. If you replace the marble and draw again, the probability of drawing another white marble is still 7/16. The net probability of drawing two white marbles, while replacing the first, is 49/256.
A marble is selected from a random jar containing 3 red marbles 4 yellow marbles and 2 marbles what are the odds in favor of selecting a red marble?
The probability of selecting a red marble is 3/9
When a jar contains 5 white marbles 3 blue marbles and 2 green marbles and if one marble is drawn at random then what is the probability that it will be blue?
There is a probability of 3 that it will be blue.
A bag contains 2 yellow 12 red and 6 green marbles What is the probability of selecting a red marble replacing it then selecting another red marble?
The probability of drawing two reds, with replacement, is the same as the probability of drawing a red, times itself. So: P(drawing two reds) = P(drawing a red)2 = (12/(2 + 12 + 6))2 = (12/20)2 = (3/5)2 = 9/25
A jar contains three colored marbles 10 red 15 green and 25 blue If you were to choose without looking what is the probability of selecting a green marble?
It is 15/50 = 0.3
If there are 3 black marbles 2 white marbles and 1 red marble what is the probability of selecting a black marble?
3/6 or 1/2 or 50%
