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

In a sample of 2023 u.s. adults, 373 said franklin roosevelt was the best president since world war ii. two u.s. adults are selected at random from the population of all u.s. adults without replacement. assuming the sample is representative of all u.s. adults, complete parts (a) through (d). (a) find the probability that both adults say franklin roosevelt was the best president since world war ii. the probability that both adults say franklin roosevelt was the best president since world war ii is (round to three decimal places as needed.) (b) find the probability that neither adult says franklin roosevelt was the best president since world war ii. the probability that neither adult says franklin roosevelt was the best president since world war ii is (round to three decimal places as needed.) (c) find the probability that at least one of the two adults says franklin roosevelt was the best president since world war ii. the probability that at least one of the two adults says franklin roosevelt was the best president since world war ii is (round to three decimal places as needed.) (d) which of the events can be considered unusual? explain. select all that apply. the event in part left parenthesis a right parenthesis is unusual because its probability is less than or equal to 0.05. the event in part (b) is unusual because its probability is less than or equal to 0.05. none of these events are unusual. the event in part (c) is unusual because its probability is less than or equal to 0.05.
