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