1) Probability of picking a blue marble = 1/4
2) Probability of picking a red marble = 3/8
3) Probability of picking a yellow marble = 3/8
4) Probability of picking a green marble = 0
The probabilities can be determined by considering the number of marbles of each color and applying the concept of probability:
1) Probability of picking a blue marble:
There are 2 blue marbles out of a total of 8 marbles.
Probability = Number of blue marbles / Total number of marbles = 2/8 = 1/4
2) Probability of picking a red marble:
There are 3 red marbles out of a total of 8 marbles.
Probability = Number of red marbles / Total number of marbles = 3/8
3) Probability of picking a yellow marble:
There are 3 yellow marbles out of a total of 8 marbles.
Probability = Number of yellow marbles / Total number of marbles = 3/8
4) Probability of picking a green marble:
There are no green marbles in the bag.
Probability = Number of green marbles / Total number of marbles = 0/8 = 0
These probabilities reflect the chances of selecting each marble color when randomly picking one marble from the bag. The total probabilities of all possible outcomes must sum up to 1, ensuring coverage of all potential events when selecting a single marble from the bag.
