Answer: The minimum reliability for the second stage be 0.979.
Step-by-step explanation:
Since we have given that
Probability for the overall rocket reliable for a successful mission = 97%
Probability for the first stage = 99%
We need to find the minimum reliability for the second stage :
So, it becomes:
P(overall reliability) = P(first stage ) × P(second stage)
Hence, the minimum reliability for the second stage be 0.979.
- Multiply x-1 on both sides
- Add 4 on both sides
- Divide both sides by 4
Now
ATQ to the equation x should be greater than 1 .Because if it becomes 1 then the denominator will be 0 which is impossible.
Hence x>1
Thus
Now
