Understanding the Problem
In this scenario, we have a box containing different colored balls. To find the probability of drawing a white ball, we need to consider the total number of balls and the number of white balls specifically.
Total Number of Balls
- Blue balls: 3
- White balls: 2
- Red balls: 4
Calculating the Total
To find the total number of balls in the box, we add the quantities of each color:
- Total = Blue + White + Red
- Total = 3 + 2 + 4 = 9
Finding the Desired Probability
The probability of an event is defined as the number of favorable outcomes divided by the total number of outcomes.
- Favorable outcomes (white balls) = 2
- Total outcomes (total balls) = 9
Calculating Probability
Using the formula for probability:
- Probability of drawing a white ball = Number of white balls / Total number of balls
- Probability = 2 / 9
Conclusion
Thus, the probability of drawing a white ball from the box is 2/9. Therefore, the correct answer is option 'C'.
