- 1
- \( \frac{1}{2} \)
- \( \frac{1}{6} \)
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The probability of an event is defined as the ratio of the number of favorable outcomes to the total number of possible outcomes.
For a sure event, the event is guaranteed to happen. This means there is no uncertainty involved, and the probability of a sure event is always 1. This is because the event will always occur.
Step 2: Conclusion.
Therefore, the probability of a sure event is \( 1 \). Final Answer:} 1.
Step 2: Conclusion.

- A bag contains 5 red, 8 white, and 7 black balls. A ball is drawn at random. Find the probability that the ball drawn is neither red nor black.
- A bag contains 10 balls out of which \( k \) are red and \( (10-k) \) are black, where \( 0 \le k \le 10 \). If three balls are drawn at random without replacement and all of them are found to be black, then the probability that the bag contains 1 red and 9 black balls is:
