Q: A box contains 5 red and 3 blue balls. What is the probability of drawing a red ball?
Solution: Total balls = 5 + 3 = 8. Probability of red = 5/8.
Steps: 5
Step 1: Count the number of red balls in the box. There are 5 red balls.
Step 2: Count the number of blue balls in the box. There are 3 blue balls.
Step 3: Add the number of red balls and blue balls together to find the total number of balls. 5 red + 3 blue = 8 total balls.
Step 4: To find the probability of drawing a red ball, divide the number of red balls by the total number of balls. This is 5 red balls divided by 8 total balls.
Step 5: Write the probability as a fraction: Probability of red = 5/8.
