An aircraft seam requires 22 rivets. The seam will have to be reworked if any of these rivets is defective. Suppose rivets are d
SpyIntel [72]

Answer:

Part A:

p=0.0095

Part B:

p=0.0043

Step-by-step explanation:

Part A:

The number of rivets=22 rivets

Probability that no rivet is defective= (1-p)^22

The probability that at least one rivet is defective=1-(1-p)^22

For 19% of all seams need reworking, probability that a rivet is defective is given by:

1-(1-p)^{22}=0.19

(1-p)^{22}=0.81\\p=1-\sqrt[22]{0.81} \\p=0.0095

Part B:

For 9% of all seams need reworking, probability of a defective rivet is:

1-(1-p)^{22}=0.09\\p=1-\sqrt[22]{0.91} \\p=0.0043
