Q: A jar contains 4 green, 5 yellow, and 6 red marbles. What is the probability of picking a yellow marble?
Solution: The total number of marbles is 4 + 5 + 6 = 15. The probability of picking a yellow marble is 5/15 = 1/3.
Steps: 6
Step 1: Count the number of green marbles. There are 4 green marbles.
Step 2: Count the number of yellow marbles. There are 5 yellow marbles.
Step 3: Count the number of red marbles. There are 6 red marbles.
Step 4: Add the number of all marbles together: 4 (green) + 5 (yellow) + 6 (red) = 15 total marbles.
Step 5: Identify how many of the total marbles are yellow. There are 5 yellow marbles.
Step 6: To find the probability of picking a yellow marble, divide the number of yellow marbles by the total number of marbles: 5 (yellow) / 15 (total) = 1/3.
