- Apply formulas, no wordings.A. A recent study found that 2% of Americans admitted they had driven while intoxicated in the prior month. If a problem asks you to find the probability that 200 or fewer people in a population of 10,000 drive under the influence of alcohol, how do you solve the problem after finding the probability in the z-table? A. Subtract one from the probability you find in the z-score tables B. The probability that equates to the z-score is the answer C. Tis problem cannot be answered with the z-tables D. Take the probability you find in the z-score tables and subtract from oneFind the probability and interpret the results. If convenient, use technology to find the probability.
