Question

hams interactive conducted a survey in which they asked adult americans (18 years or older) whether they used social media (facebook, twitter, and so on) regularly. the following table is a subsample based on the results of the survey. complete parts (a) through (d). click the icon to view the table. (a) if an adult american is randomly selected, what is the probability they use social media? p(use social media) = (round to three decimal places as needed.)

Explanation:

Step1: Recall the probability formula

The probability formula is \(P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\). Here, the event \(A\) is "use social media". The number of favorable outcomes is the number of people who use social media, which is \(323\). The total number of outcomes is the total number of people surveyed, which is \(504\).

Step2: Calculate the probability

Substitute the values into the formula: \(P(\text{use social media})=\frac{323}{504}\approx0.641\)

Answer:

\(0.641\)
