Question
is a random variable with uniform probability density function in the interval . For , the conditional probability (rounded off to three decimal places) is _________.
Correct answer
0.299 to 0.301
Solution
Given that is a uniform random variable in the interval .
The probability density function (PDF) of is:We need to find the conditional probability .First, let's express the condition in terms of :
Given .
.So, the required probability is .
Using the definition of conditional probability, .
Here, and .
The intersection is , which simplifies to .Now, we calculate :Next, we calculate :Finally, we compute the conditional probability:Rounded off to three decimal places, the answer is .The final answer is .
