Given that the first component drawn is defective, there are now 299 defective components out of a total of 999 components. Therefore, $P(B|A) = \frac{299}{999} \approx 0.2993$.

A Lot of 1000 Components Contains 300 That Are Defective Find P(B∣A). \text { Find } P ( B \mid A ) \text {. } Find P(B∣A).
