11/19 or just under 58 % it will be red, just under 16 % of the time it will be blue and a little over 26 % it will be green
There is a probability of 3 that it will be blue.
100%
The probability is 19/25 * 18/24 = 0.57

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

If there is 3 blue 2 red and 4 green. What is the probability of getting green?
Yes, those events can be found.
There is a probability of 3 that it will be blue.
The probability of choosing a blue marble is 5 in 15 or 1 in 3. The probability of then choosing a green marble is 5 in 14. (One is missing) Multiply the two probabilities and you get 5 in 42.(P = 0.1190... about 12%).

The probability is 0.56
This is the same as the probability of choosing either a red of a blue marble. There are 5+4 out of 15 ways of doing this. The probability is therefore 9/15 = 3/5.
There are 16 marbles total and 7 green ones, so the probability is 7/16.

The probability is 19/25 * 18/24 = 0.57
