In a sample of 1000 U.S Adults 216 dine out at a restaurant more than once a week. 2 US adult are selected at random from the population of all US adults without replacement. Assuming the example is representative of all US adults complete parts a through d. a.) The probability that both adults dine out more than once a week is ____(round to three decimal points) b.) Find the probability that neither adult dines out more than once a week. c.) Find the probability that at least one of the two adults dines out more than once a week. d.) which events can be described as unusual and why

Step 1
- Probability that the first adult dines out more than once a week: \( \frac{216}{1000} = 0.216 \) - Probability that the second adult also dines out more than once a week (without replacement): \( \frac{215}{999} = 0.215 \) - Probability that both adults dine out Show more…

Dining Out In a sample of 1000 U.S. adults, 180 dine out at a restaurant more than once per week. Two U.S. adults are selected at random without replacement. (Adapted from Rasmussen Reports) (a) Find the probability that both adults dine out more than once per week. (b) Find the probability that neither adult dines out more than once per week. (c) Find the probability that at least one of the two adults dines out more than once per week. (d) Which of the events can be considered unusual? Explain.

Sample of 1000 U.S. adults. 150 said they are very confident in the nutritional information. They are selected at random without replacement. Find the probability that all four adults are very confident in the nutritional information on restaurant menus. Round to 4 decimal places. Find the probability that none of the four adults are very confident in the nutritional information on restaurant menus. Round to 3 decimal places. Find the probability that at least one of the four adults is very confident in the nutritional information on restaurant menus. Round to 3 decimal places. Which of the events (a, b, or c) can be considered unusual?

To investigate how often families eat at home, Harris Interactive surveyed 496 adults living with children under the age of $18(U S A \text { Today, January } 3,2007$ ). The survey results are shown in the following table. For a randomly selected family with children under the age of $18,$ compute the following. a. The probability the family eats no meals at home during the week. b. The probability the family eats at least four meals at home during the week. c. The probability the family eats two or fewer meals at home during the week.
