Questions & Step-by-Step Solutions
In a box of 100 balls, 30 are red, 50 are blue, and 20 are green. What is the probability of picking a red ball?
Step 1: Identify the total number of balls in the box. There are 100 balls.
Step 2: Identify how many of those balls are red. There are 30 red balls.
Step 3: Use the formula for probability, which is: Probability = (Number of favorable outcomes) / (Total outcomes).
Step 4: Substitute the numbers into the formula: Probability = 30 (red balls) / 100 (total balls).
Step 5: Calculate the probability: 30 divided by 100 equals 0.3.
