The lifetime (X) of a bulb has an exponential distribution with a mean value of (E(X)=8000) hours.

Question:

The lifetime $X$ of a bulb has an exponential distribution with a mean value of $E(X)=8000$ hours. Calculate the probabilities

\[P(X \leq 4000), P(X>12000), \quad P(7000 \leq X<9000), \text { and } P(X<4000)\]

(time limits in hours).
