Sixty percent of U.S. mothers with school-age children choose fast-food as a dining option for their families one to three times a week. You randomly select five U.S. mothers with school-age children and ask them whether they choose fast-food as a dining option for their families one to three times a week. The random value represents the number of mothers who choose fast food one to three times a week. Calculate the probability that two mothers in your sample choose fast food once to three times a week. Using the table determine the probability that more than two mothers choose fast food once to three times a week. What is the mean of this distribution? What is the standard deviation?
