(Satellite Operation) The Earth rotating satellite has a sensor
whose operating time X (in units per year) follows the exponential
distribution as λ = 0.6. Then, X has a density function
f (t) =( λe − λt, t> 0,
0, t ≤ 0)
(a) Determine the accumulation function F (t) of X.
(b) Calculate the probability that the sensor will last at least
seven years.
(c) Determine the accumulation function for the conditional
distribution of the random variable Y = X - 7 with respect to event
A = {X> 7}, ie the function FY | A (t) = P (Y ≤ t | A).
(d) Calculate the probability that the sensor will last at least
another seven or seven years if it is known to be intact even after
the first seven years.
