andre [41]

Answer: 0.074

Step-by-step explanation:

Given : The total number of U.S. adults in the sample = 800

The number of U.S. adults dine out at a restaurant more than once a week = 216

The probability for an adult dine out more than once per week :-

$\dfrac{218}{800}$

If another person is selected without replacement ,then

Total adults left = 799

Total adults left who dine out at a restaurant more than once a week = 217

The probability for the second person dine out more than once per week :-

$\dfrac{217}{799}$

Now, the probability that both adults dine out more than once per week :-

$\dfrac{218}{800}\times\dfrac{217}{799}=0.074$
