on average at rate of one per 2 seconds. Due to high frequency clock, we can treat the arrival time of these interrupts as an exponential random variable. At t = 0, the counter of interrupts was reset to 0. After checking the counter at t = 3 seconds, you learn that one interrupt was received. What is the expected arrival time of that interrupt?

A microcontroller receives a particular interrupt
on average at rate of one per 2 seconds. Due to
high frequency clock, we can treat the arrival
time of these interrupts as an exponential
random variable. At t = 0, the counter of
interrupts was reset to 0. After checking the
counter at t = 3 seconds, you learn that one
interrupt was received. What is the expected
arrival time of that interrupt?
