b.

In the event that the likelihood of landing securely should be at any rate 99.5%, what is the scaled down-

mum incentive for p?

Rehash the inquiry for likelihood of landing securely to

be 99.9%.

c.

On the off chance that the unwavering quality can't be improved past 92% yet the quantity of

motors in a plane can be expanded, what is the base number of

motors that would accomplish in any event 99.5% likelihood of landing securely?

Rehash for 99.9% likelihood.

d.

One would positively want 99.9% likelihood of landing securely. Looking

at the responses to (b) and (c

), what might you say is a superior methodology
