Introduction:
In a musical chairs game, the person playing the music has been advised to stop playing the music at any time within 2 minutes after she started playing. We need to find the probability that the music will stop within the first half minute after starting.
Understanding the Problem:
To solve this problem, we need to determine the favorable outcomes and the total number of possible outcomes. The probability is then calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
Favorable Outcomes:
The favorable outcomes in this case are when the music stops within the first half minute after starting. Since the music can be stopped at any time within the first 2 minutes, the favorable outcomes can range from 0 seconds to 30 seconds.
Total Number of Possible Outcomes:
The total number of possible outcomes is the total time duration within which the music can be stopped. In this case, it is 2 minutes, which is equal to 120 seconds.
Calculating the Probability:
To calculate the probability, we divide the number of favorable outcomes by the total number of possible outcomes.
Number of favorable outcomes = 30 seconds
Total number of possible outcomes = 120 seconds
Probability = Number of favorable outcomes / Total number of possible outcomes
Probability = 30 seconds / 120 seconds
Probability = 1/4 or 0.25
Conclusion:
The probability that the music will stop within the first half minute after starting is 0.25 or 25%.

Probability = 30 seconds / 120 seconds
Probability = 1/4 or 0.25

The probability that the music will stop within the first half minute after starting is 0.25 or 25%.
