n= 1000

p= .20

Why is p = .20 and could you show me how to get to this answer?

2)A massive rocket with 3000 computer chips in its control systems is engineered so that the rocket will work as designed even if 60 chips fail. The chip manufacturer can only guarantee that individual chips will fail at random no more than one and a half percent of the time. Estimate the likelihood that the rocket will fail.

n= 3000

p=0.015

Why is p = 0.015 and could you show me how to get to this answer please?

Thanks and all help is appreciated!
