(c) Let X have an exponential density with parameter λ > 0, Prove the "memoryless" property: P(X > t + s|X > s) = P(X > t) for t>0 and s 0. For example, the probability that the conversation lasts at least t more minutes is the same as the probability of it lasting at least t minutes in the first place.

Recall that X ∼ Exp(λ) if the probability density function of X
is fX(x) = λe−λx for x ≥ 0. Let X1, . . . , Xn ∼ Exp(λ), where λ is
an unknown parameter. Exponential random variables are often used
to model the time between rare events, in which case λ is
interpreted as the average number of events occurring per unit of
time.
Recall that X ~ Exp(A) if the probability density function of X is fx(x)-Ae-Az for...

9. Let X have an exponential distribution with λ = 1 (see Question 5), and let Y = log(X). Find the probability density function of Y. Where is the density non-zero? Note that in this course, log refers to the log base e, or natural log, often symbolized In. The distribution of Y is called the (standard) Gumbel, or extreme value distribution. 2
