Question: If a box contains 3 red balls, 2 blue balls, and 5 green balls, what is the probability of picking a blue ball?

Options:

Correct Answer: 1/5

Solution:

Total balls = 3 + 2 + 5 = 10. Probability of blue ball = 2/10 = 1/5.

If a box contains 3 red balls, 2 blue balls, and 5 green balls, what is the probability of picking a blue ball?

Step 1: Count the number of red balls. There are 3 red balls.
Step 2: Count the number of blue balls. There are 2 blue balls.
Step 3: Count the number of green balls. There are 5 green balls.
Step 4: Add the total number of balls together: 3 (red) + 2 (blue) + 5 (green) = 10 total balls.
Step 5: Identify how many of the total balls are blue. There are 2 blue balls.
Step 6: Calculate the probability of picking a blue ball by dividing the number of blue balls by the total number of balls: 2 (blue) / 10 (total) = 2/10.
Step 7: Simplify the fraction 2/10 to its lowest terms: 2/10 = 1/5.
