A beverage company runs a promotion for free soft drinks. When a customer buys a drink, they look inside the cap. If it says "Winner,” the customer receives a free drink; otherwise, the cap will say "Try Again.” The company states that one out of every four purchases will be a "Winner.” Five friends each buy one beverage. What is the mean and standard deviation of the number in this group who will purchase a "Winner” drink? mean = 0.25, standard deviation = 1.25
mean = 1.25, standard deviation = 0.94
mean = 1.25, standard deviation = 0.97
mean = 5, standard deviation = 0.94
mean = 5, standard deviation = 0.97
