M&M's candies are 16% green. If we took a lot of samples, each with 100 M&M's, we'd expect about 16 greens in each sample. The distribution of the number of green M&M's is normal, with mean 16 and standard deviation 3.7. a) What's the probability a sample has 18 or more green M&Ms?

b) What's the probability a sample has 15 or fewer green M&Ms?

c) What number of green M&Ms are in the samples with the lowest 20% of greens?
