Can you explain how you would get the standard deviation and even though it doesn't ask for it but the mean too? That's what I mostly struggle with.

A mom walks into her child's room and finds clothes all over the floor. 20% of the clothes are clean. She randomly picks up 5 articles of clothing. 1. We can expect 1 out of 5 articles of clothing to be clean. 2. The standard deviation is (Round to the nearest tenth, if necessary.) 3. Because the distribution has a probability of success (P(S)) that is close to .5 the distribution is close to skewed right (positive) 4. Use the probability formula P(r) =. Cop/q" to create a binomial distribution table. P(r) Probability formula Enter the probability only. Round to the tenth, if necessary. Round to the 4th decimal place, if necessary. 5
