The fraction of shipments that will be accepted is 0.1299.
<h3>
How to calculate the probability?</h3>
Probability of a defective DVD = 0.04
Using Binomial distribution,
Fraction of shipments accepted = Probability of zero defects in sample of 50 = P(X = 0)
= 50C0 * 0.040 * (1 - 0.04)⁵⁰
= 0.96⁵⁰
= 0.1299
Fraction of shipments accepted = Probability of zero or one defects in sample of 50 = P(X = 0) + P(X = 1)
= 50C0 * 0.040 * (1 - 0.04)50-0 + 50C1 * 0.041 * (1 - 0.04)50-1
= 0.9650 + 50 * 0.04 * 0.9649
= 0.4005
