Question 1154996: A manufacturer of window frames knows from long experience that 20% of the production will have some type of minor defect that will require an adjustment. What is the probability that in a sample of 16 window frames:

a. None will need adjustment? (Round the final answer to 3 decimal places.)

Probability
0.028

b. At least one will need adjustment? (Round the final answer to 3 decimal places.)

Probability
0.972

c. More than two will need adjustment? (Round the final answer to 3 decimal places.)

Hi  

n = 16, p = .2 defective

c. More than two will need adjustment? (Round the final answer to 3 decimal places.) 

P(More than two will need adjustment) = 1 - P(2 or less)



P(More than two will need adjustment)= 1- binomcdf(16,.2, 2)

Wish You the Best in your Studies.
