A bag with 12 marbles has 3 yellow marbles, 4 blue marbles, and 5 red marbles. A marble is chosen from the bag at random. What is the probability that it is yellow?
A bag with marbles has blue marbles, yellow marbles, and red marbles. A marble is chosen from the bag at random. What is the probability that it is blue?
To find the probability of selecting a yellow marble, we need to determine the total number of marbles in the bag and the number of yellow marbles.
The total number of marbles in the bag is 12. We can then determine the probability by dividing the number of yellow marbles (which is 3) by the total number of marbles in the bag:
Probability of selecting a yellow marble = Number of yellow marbles / Total number of marbles
Probability of selecting a yellow marble = 3 / 12
Simplifying, we get:
Probability of selecting a yellow marble = 1 / 4
Therefore, the probability of selecting a yellow marble is 1/4 or 0.25.
Hey fellow student! The total number of marbles is 12. Because:
5 red marbles + 4 blue marbles + 3 yellow marbles = 12 total marbles
And there are 3 YELLOW marbles in the special bag . . .
So the probability of a yellow marble would be 3/12. The reason why is because there are 3 TOTAL yellow marbles and there are 12 TOTAL marbles.
Hope this helps!
