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)

0.97=0.99\times x\\\\\dfrac{0.97}{0.99}=x\\\\0.979=x

Hence, the minimum reliability for the second stage be 0.979.

We know they combine to 2,977 grams. The puppies weight the same
Let’s make puppy = x
Basket weight = 1,077
8x + 1077 = 2977
8x = 1900, x = 237.5 grams
It would be around 250 grams
