How do you solve this 10 percent of m nd m plain candies are blue if a sample of 20 m nd ms is randomly selected find P of it will be more than 15 blue candies?

If 10% of plain M&Ms are blue and you have a sample of 20 M&Ms only two of them will be blue. If you need to have 15 blue M&Ms, then your sample size should be 150 M&Ms because 15 is 10% of 150.
