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.
Answer:
$60
Step-by-step explanation:
This is because 400 times 0.03 is 12 and 12 times 5 is 60
To solve this, you just divide 20 divided by 7.
20/7 = <span>2.85714285714
If you are trying to round to the nearest tenth, the next decimal place (hundredths) is a 5, so you must round 2.8 up one more digit.
Your final answer is that</span> 20/7 = 2.9 when rounded to the nearest tenth.
