Question:
Let \(X\) denote the time between detections of a particle with a Geiger counter and assume that \(X\) has an exponential distribution with \(E(X)=1.4\) minutes. The probability that we detect a particle within 0.5 minute of starting the counter is
\[ P(X<0.5)=F(0.5)=1-e^{-0.5 / 1.4}=0.30 \]
Now, suppose that we turn on the Geiger counter and wait 3 minutes without detecting a particle. What is the probability that a particle is detected in the next 30 seconds?
