Binomial Random Variable According to the CDC, in 2015 20% of high school students rode with a driver (in the last 30 days) who had been drinking alcohol. A random sample 16 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. You may get a slightly different answer due to rounding if you use a calculator or other technology. 1. At least 15 have ridden with a drunk driver. P(r 2 + v 15) = 0 2. Less than 4 have ridden with a drunk driver. P(r < ¢ v 4) = 0.5981 3. No more than 2 have ridden with a drunk driver. P(rse V 2) =| 0.3518 4. Exactly 11 have ridden with a drunk driver. P(r = v 11) 0.029 5. At least 1 have ridden with a drunk driver. P(r 2 + v 1) =| 0.9719 6. Between 2 and 4 (exclusive) have ridden with a drunk driver. P(2 < v r V 4) = 0.24629
