In a musical chair game, the music can stop at any time within 2 minutes. What is the probability that it stops within the first half-minute?
Solution:
The music can stop anytime between 0 to 2 minutes — this is the total time range.
We want to find the probability that it stops within the first 30 seconds (half a minute).
So,
- Total possible time = 2 minutes
- Favourable time = 0 to 0.5 minutes (half-minute)
P(within half-minute) = 0.5/2 = 1/ 4
