A box contains 3 red, 2 blue, and 5 green balls. What is the probability of drawing a green ball?

• A. 1/3
• B. 1/2
• C. 1/5
• D. 2/5

Answer: (B)

To find the probability of drawing a green ball from the box, you need to follow these steps:

First, calculate the total number of balls in the box. The box contains:

• 3 red balls

• 2 blue balls

• 5 green balls

Adding these together gives:

3 (red) + 2 (blue) + 5 (green) = 10 balls in total.

Next, to find the probability of drawing a green ball, you take the number of green balls and divide it by the total number of balls. There are 5 green balls in the box, so the calculation is:

Probability of drawing a green ball = Number of green balls / Total number of balls = 5 / 10.

Simplifying this fraction results in:

5 / 10 = 1 / 2.

Therefore, the probability of drawing a green ball is 1/2. This shows that the likelihood of selecting a green ball from the collection of different colored balls gives a straightforward and clear understanding of how many successful outcomes (drawing a green ball) there are compared to the total possible outcomes (total balls).
