The Board of Directors for the Center has asked a polling company to survey all of the new visitors to the slavery and lynching memorial you’ve helped to develop. Over the first month more than 50,000 people have come to Montgomery, Alabama to visit the memorial. 60% of all visitors were Black. Over the second two weeks after the grand opening, the polling company asked random visitors to evaluate who they more like to bring each to visit the memorial of each of the following groups of people:
• their child
• their parent
• their friend who is Black
• their friend who is White
• their friend who is a person of color but not Black

19. If these choices are all equally possible, what is the likelihood that visitors would most likely choose to bring their child or parent to visit the memorial?
The polling company predicted that most Black people would choose to bring their friend or parent rather than their child.

20. If of the first 275 Black people surveyed, 125 said they would rather choose to bring their child, while 85 said they would bring their parent and 65 said they would bring one of their friends, was the polling company’s prediction correct? Explain using mathematical calculations and reasoning.
