A continuous random variable is uniformly distributed on the interval from 2 to 8. What is the probability that it lies between 3 and 5?
Correct answer: B. 1/3
- A. 1/6
- B. 1/3
- C. 1/2
- D. 2/3
Explanation
For a uniform distribution, probability equals the length of the required interval divided by the total length. Therefore, P(3 < X < 5) = (5 - 3)/(8 - 2) = 1/3.
