Ultrasound is a widely used technique to predict the sex of an infant before birth, however, sometimes the prediction is incorrect. Information is available on 1000 births, of which 480 were female and 520 were male. Of the 480 female births, 48 of them were predicted to be male by ultrasound, while of the 520 male births, 75% of them were correctly predicted by ultrasound. If a newborn is chosen at random from this population: (a) What is the probability that the ultrasound predicted that the infant would be female? (b) What is the probability of the ultrasound test being correct when it predicts that the unborn infant will be female? (c) What is the probability of the ultrasound test being correct when it predicts that the unborn infant will be male? Plzz solved all question then i will rate you
A lot contains 20 articles. The probability that the lot contains exactly two defective articles is 0.4 and the probability that it contains exactly 3 defective articles is 0.6. Articles are drawn from the lot at random one by one without replacement and are tested till all defective articles are found. Then find the probability that the testing procedure ends at the twelfth testing.
