The popular candy Skittles comes in 5 colors. According to the Skittles website, the 5 colors are evenly distributed in the population of Skittle candies. So each color makes up 20% of the population. Suppose that we purchase a mid-size bag of Skittles. Assume this size bag always has 200 candies. In this particular bag, 50 are green. What is the probability that a randomly selected bag of this size has 50 or more green candies? (Note: the answer may vary slightly due to rounding in the calculation of the Z-score.)

The probability that a randomly selected bag of 200 candies has 50 or more green candies is P=0.04.

Step-by-step explanation:

We have a population with green candies proportion p=0.2.

If the bag comes with n=200 candies, then the mean green candies per bag is:

The standard deviation is:

We have to calculate the probability that an individual bag has 50 green candies out of 200. We will then calculate the z-score:

The probability of having 50 or more green candies per bag is then:
