Q
Q: A box contains 10 balls: 4 blue, 3 green, and 3 red. What is the probability of drawing a red ball?
Solution:
The total number of balls is 10. The probability of drawing a red ball is 3/10.
Steps: 6
Show Steps
Step 1: Count the total number of balls in the box. There are 4 blue, 3 green, and 3 red balls.
Step 2: Add the number of balls together: 4 (blue) + 3 (green) + 3 (red) = 10 (total balls).
Step 3: Count how many of the balls are red. There are 3 red balls.
Step 4: To find the probability of drawing a red ball, use the formula: Probability = (Number of red balls) / (Total number of balls).
Step 5: Substitute the numbers into the formula: Probability = 3 (red balls) / 10 (total balls).
Step 6: The probability of drawing a red ball is 3/10.
