Question

In a poll, respondents were asked whether they had ever been in a car accident. 348 respondents indicated that they had been in a car accident and 247 respondents said that they had not been in a car accident If one of these respondents is randomly selected, what is the probability of getting someone who has been in a car accident? Round to the nearest thousandth, if necessary. 13) A botch consists of 12 defective coils and 88 good ones. Hind the probability of getting two good coils when two coils arc randomly selected if the first selection is replaced before the second is made.

Explanation / Answer

12. P(Car accident) = 348 / (348+247) = 0.5849

13. P(Good coil selected) = 88/100 = 0.88

P(2 good coils selected) = 0.882 = 0.7744
