Websites for small businesses. Visual Objects, a portfolio website, surveyed 529 small businesses about whether they have a website, why they have a website, and how they maintain their website. The 2019 survey found that 317 small businesses have a website, 117 currently have no website but have plans to create one, and 95 have no website and have no plans for one in the future. Of the 317 small businesses with a website, 70 invested in the website in order to build brand awareness. Of the 212 small businesses without a website, 28 use social media for their web presence. One of the 529 small businesses is randomly selected, and its web- site status is determined. Define the following events. A = {The small business currently has a website} B = {The small business is currently without a website} C: = {The small business invested in the website in order to build brand awareness} D = {The small business is without a website, but uses social media for their web presence} a. Find P(A). b. Find P(B). c. Find P(CA). d. Find P(DB). e. Find P(ANB). f. Find P(BOD).
