In a sample of 900U.S.adults,194dine out at a resaurant more than once per week. TwoU.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 dine out more than once per week.The probability that both adults dine out more than once per week is nothing. (Round to three decimal places asneeded.)
(b) Find the probability that neither adult dines out more than once per week.The probability that neither adult dines out more than once per week is nothing. (Round to three decimal places asneeded.
)(c) Find the probability that at least one of the two adults dines out more than once per week.The probability that at least one of the two adults dines out more than once per week is nothing.(Round to three decimal places asneeded.)
(d) Which of the events can be consideredunusual? Explain. Select all that apply.
A.The event in part left parenthesis a right parenthesis is unusual because its probability is less than or equal to 0.05Theeventinpart(a)isunusualbecauseitsprobabilityislessthanorequalto0.05.
