29-year-olds via social media. Suppose a study found that 36% of adults (18 and older) do not
use social media. Suppose the percentage of adults age 30 and older is 75%. Suppose that the
percentage of the adult population that is either age 18-29 or uses social media is 64%.
What is the probability that a randomly selected adult is 18-29 and a user of social media?
Your answer should be expressed as a number between 0 and 1, and it has to contain 2
decimal places.
