1.There is a die that has only four sides. All of them are different colors (orange, yellow, green, and blue), and all of them are equally likely. This die is rolled five times. What is the probability of getting a blue side exactly twice?

2.If you drew the binomial distribution for the number of times you get a blue side when you roll it five times, what would the standard deviation of this distribution be?

3. show the work for me please.
