A box contains 3 red balls and 2 blue balls. What is the probability of picking a red ball? (2023)

Step 1: Identify the total number of balls in the box. There are 3 red balls and 2 blue balls.
Step 2: Calculate the total number of balls by adding the red and blue balls together: 3 (red) + 2 (blue) = 5 (total balls).
Step 3: Identify the number of favorable outcomes, which is the number of red balls. There are 3 red balls.
Step 4: Use the probability formula: Probability = Number of favorable outcomes / Total outcomes.
Step 5: Substitute the numbers into the formula: Probability = 3 (red balls) / 5 (total balls).
Step 6: Simplify the fraction: 3/5.
Step 7: Convert the fraction to a decimal if needed: 3/5 = 0.6.

Probability – The likelihood of an event occurring, calculated as the ratio of favorable outcomes to total outcomes.
