1. The Census Bureau's Current Population Survey shows that 28% of individuals, ages 25 and older, have completed four years of college. For a sample of 15 individuals, ages 25 and older, what is the probability that eight or more will have completed four years of college? (Hint: consider as a binomial)

2. Refer to speeds at which cars pass through a checkpoint on the highway. Assume the speeds are normally distributed with a population mean of 61 miles per hour and a population standard deviation of 4 miles per hour. Calculate the probability that the next car passing will be travelling more than 58 miles per hour.
