According to a recent survey, 40% of millennials (those born in the 1980s or 1990s) view themselves more as ‘spenders’ than ‘savers’. The survey also reveals that 75% of millennials view social networking as important to find out about products and services. A social media expert wants to determine the probability that a randomly selected millennial either views themselves as a ‘spender’ or views social networking as important to find out about products and services. Can this question be answered? Under what conditions can it be solved? If the problem cannot be solved, what information is needed to make it solvable?
