Answer:
The reliability of the first system to work is 0.72 whereas the reliability of the second system to work is 0.98.As the reliability of the second system is more than the first one so the second system is more reliable.
Step-by-step explanation:
For first system as given in the attached diagram gives,
As the systems are independent.
The given data indicates that
is given as 0.9
is given as 0.8
Now the probability of the system is given as
So the reliability of the first system to work is 0.72.
For the second system is given as
Where
is the probability where both of the systems does not work. this is calculated as
So now the probability of the second system is given as
So the reliability of the second system to work is 0.98.
As the reliability of the second system is more than the first one so the second system is more reliable.
