Questions & Step-by-Step Solutions
A box contains 5 red, 3 green, and 2 blue balls. What is the probability of drawing a green ball?
Step 1: Count the total number of balls in the box.
Step 2: Add the number of red balls (5), green balls (3), and blue balls (2).
Step 3: Total balls = 5 + 3 + 2 = 10.
Step 4: Identify how many of the balls are green.
Step 5: There are 3 green balls.
Step 6: To find the probability of drawing a green ball, use the formula: Probability = (Number of green balls) / (Total number of balls).
Step 7: Substitute the numbers: Probability = 3 / 10.
Step 8: The probability of drawing a green ball is 3/10.
