Q: A box contains 10 balls: 3 are red, 4 are blue, 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 4/10 = 2/5.
Steps: 6
Show Steps
Step 1: Count the total number of balls in the box. There are 3 red, 4 blue, and 3 green balls.
Step 2: Add the number of balls together: 3 (red) + 4 (blue) + 3 (green) = 10 (total balls).
Step 3: Identify how many of the balls are blue. There are 4 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 = 4 (blue balls) / 10 (total balls).
Step 6: Simplify the fraction 4/10 to get 2/5.
