Math Problem Statement
Solution
The question is about a uniform distribution of a random variable , and you are asked to find the probability or from the given uniform distribution over the interval [0, 2].
For a uniform distribution over an interval , the probability density function (PDF) is given by:
Here, and , so the PDF is:
The probability of being in any subinterval is simply the length of that subinterval multiplied by the PDF. Thus, to compute the probabilities:
- :
The length of the interval is:
So, the probability is:
- :
The length of the interval is:
So, the probability is:
- For or :
Since these two events are mutually exclusive (they can't happen at the same time), you can add the probabilities:
Thus, the final answer is 0.26.

Tip: Always visualize the interval on the number line for uniform distributions to better understand the probabilities associated with different regions.
