Question: A box contains 5 red balls and 3 blue balls. If one ball is drawn at random, what is the probability that it is blue?

A box contains 5 red balls and 3 blue balls. If one ball is drawn at random, what is the probability that it is blue?

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. Total balls = 5 + 3 = 8.
Step 4: Identify how many of the total balls are blue. There are 3 blue balls.
Step 5: Calculate the probability of drawing a blue ball by dividing the number of blue balls by the total number of balls. Probability = Number of blue balls / Total balls = 3 / 8.
