Question

in a particular survey of internet users, 3660 respondents say that they use social networking sites and 1353 respondents say that they do not use social networking sites. what is the probability that a randomly selected person uses a social networking site? does that result suggest that it is likely (with a probability of 0.5 or greater) for someone to use social networking sites? the probability that a randomly selected person uses a social networking site is (round to three decimal places as needed.)

Explanation:

Step1: Find total number of respondents

Total = 3660 (users) + 1353 (non - users) = 5013

Step2: Calculate probability

Probability = $\frac{\text{Number of users}}{\text{Total number of respondents}}$ = $\frac{3660}{5013}$
Now, calculate $\frac{3660}{5013}\approx0.730$ (rounded to three decimal places)

Answer:

0.730
