Understanding the Problem
To find the probability of drawing either a red or black ball from the bag, we first need to know the total number of balls and the number of favorable outcomes.
Contents of the Bag
- 4 red balls
- 6 black balls
- 5 white balls
Total Number of Balls
- Total = Red + Black + White
- Total = 4 + 6 + 5 = 15 balls
Favorable Outcomes
- The favorable outcomes for drawing a red or black ball are:
- Red balls = 4
- Black balls = 6
- Total favorable outcomes = Red + Black = 4 + 6 = 10
Calculating Probability
- Probability of an event = (Number of favorable outcomes) / (Total number of outcomes)
- Probability of drawing a red or black ball = 10 / 15
Simplifying the Probability
- To simplify 10/15:
- Divide both the numerator and the denominator by 5.
- 10 ÷ 5 = 2
- 15 ÷ 5 = 3
- Thus, the simplified probability = 2/3
Conclusion
The probability of drawing a red or black ball from the bag is 2/3, which corresponds to option 'A'.
