Answer is: x=3
Add the two equations together to eliminate y from the system.
Then divide each term by 5 and simplify.
Write it as a mixed fraction 7/5 = 1 2/5
The answer to the question is d
Answer: Our required probability is 0.39.
Step-by-step explanation:
Since we have given that
X be the exponentially distributed with mean life = 6 years
So, E[x]=6

So, our cumulative distribution function would be

We need to find the probability that the CPU fails within 3 years.

Hence, our required probability is 0.39.
I think it is -2, if that helps
