According to the CDC, in 2015 15% of high school students rode with a driver (in the last 30 days) who had been drinking alcohol. A random sample 12 high school students was chosen. Assume the distribution is normal. Use the Binomial Distribution Table (PDF, 739 KB) (opens in new window) to find the probabilities. Please note, this question is specifically assessing your ability to use the table to find the probability.
