Step-by-step explanation:
Let X be the exponential random variable that represents the lifetime of a computer.
i.e.
The probability that the computer will function more than 2000 days can be computed as follows:
P(X > 2000)
:
P(X > 2000) = 1 - P(X< 2000)
P(X > 2000) = exp(-2000/β) = e⁻²²
P(X > 2000) = 0.108368
