In a bag, if there are 5 blue balls, 6 red balls, and 11 white balls. What is the probability that if one ball is pulled out of the bag, it is white?
Answer: 0.5
Explanation
1. Count the number of desired outcomes:
- There are 11 white balls.
2. Count the total number of possible outcomes:
- There are 5 blue balls.
- There are 6 red balls.
- There are 11 white balls.
- Add these numbers together: 5 + 6 + 11 = 22 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 = 11 / 22 = 0.5
Therefore, the probability of pulling out a white ball from the bag is 0.5, or 50%.
