In a bag, if there are 7 red balls, 8 white balls, and 9 green balls, what is the probability that a ball pulled out of the bag will be red, green, or white?

Answer: 1
Explanation

1. Count the number of desired outcomes:

- There are 7 red balls.

- There are 9 green balls.

- There are 8 white balls.

- Add these numbers together: 7 + 9 + 8 = 24 desired outcomes.

2. Count the total number of possible outcomes:

- There are 7 red balls.

- There are 8 white balls.

- There are 9 green balls.

- Add these numbers together: 7 + 8 + 9 = 24 possible outcomes.


3. Calculate the probability by dividing the number of desired outcomes by the total number of possible outcomes:

- Probability = Number of desired outcomes / Total number of possible outcomes

- Probability = 24 / 24 = 1


Therefore, the probability of pulling out a red, green, or white ball from the bag is 1, or 100%.
