The manufacturer of M&M's candies states that 16% of the candies are green. You pick a large bag at random that contains 200 candies and find 20% of the candies are green. What's the probability of getting a sample proportion of green M&M's of 20% or higher?

If the M&M candy company guarantees us that 15% of its candies are yellow, what would be the probability of randomly picking exactly 2 yellow candies, out of 20 attempts (i.e. trials)? Please round your answer to the nearest 2 decimal places.

A bag contains 25 gumballs in total. There are 6 blue gumballs, 7 green gumballs, 4 red gumballs, 3 yellow gumballs, and 5 black gumballs. What is the probability that when you draw 4 gumballs at random from the previously described bag of 25 gumballs, all 4 of them happen to be green?
