Answer:
The probability of the system being down in the next hour of operation is 0.3.
Step-by-step explanation:
We have a transition matrix from one period to the next (one hour) that can be written as:
We can represent the state that system is initially running with the vector:
The probabilties of the states in the next period can be calculated using the matrix product of the actual state and the transition matrix:
That is:
With the inital state as running, we have a probabilty of 0.7 that the system will be running in the next hour and a probability of 0.3 that it will be down.
