WebThe desired probability is P(X > 30 X > 10). Since exponential random variables have memoryless property, we have P(X > 30 X > 10) = P(X > 20) = 1−P(X ≤ 20) = e−1 ≈ 0.3679 The probability function of an uniform random variable with parameter 0 WebOct 4, 2024 · Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their …
