In hawaii, january is a favorite month for surfing since 60% of the days have a surf of at least 6 feet.† you work day shifts in a honolulu hospital emergency room. at the beginning of each month you select your days off, and you pick 5 days at random in january to go surfing. let r be the number of days the surf is at least 6 feet.(b) what is the probability of getting 4 or more days when the surf is at least 6 feet? (round your answer to three decimal ) what is the probability of getting fewer than 2 days when the surf is at least 6 feet? (round your answer to three decimal ) what is the expected number of days when the surf will be at least 6 feet? (round your answer to two decimal days(e) what is the standard deviation of the r-probability distribution? (round your answer to three decimal days(f) can you be fairly confident that the surf will be at least 6 feet high on one of your days off? explain. (round your answer to three decimal places.)yes, because the probability of at least 1 day with surf of at least 6 feet is and the expected number of days when the surf will be at least 6 feet is greater than one.

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.
