Here's my question and I also attached the binomial distribution table to help!

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. You may get a slightly different answer due to rounding if you use a calculator or other technology. 1. At least 11 have ridden with a drunk driver. P(r 15) 2. Less than 4 have ridden with a drunk driver. P(r 4): 3. No more than 2 have ridden with a drunk driver. P(r 2) = 4. Exactly 9 have ridden with a drunk driver. P(r 1 1) = 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) =Binomial Probability Distribution Distribution Formula: "Crpq-r This table shows the probability of r successes in n independent trials, each with probability of success p.
