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 (opens in new window) to find the probability that: 1. At least 15 have ridden with a drunk driver. P(r : 15) 2. Less than 4 have ridden with a drunk driver P(r • 4) %3D 3. No more than 2 have ridden with a drunk driver, P(r • 2) = 4. Exactly 11 have ridden with a drunk driver. + P(r : 11) = 5. At least 1 have ridden with a drunk driver. P(r • 1) = 6. Between 2 and 4 (exclusive) have ridden with a drunk driver. P(2 : 4) V.
