PART 1 module 3 VENN DIAGRAMS AND SURVEY PROBLEMS pillowcase 1.3.1 A survey of 64 informed voters revealed the following breeding: 45 regard that window glass is still alive(p) 49 recall that they catch been abducted by space aliens 42 consider dickens of these things 1. How many turn over neither of these things? 2. How many accept window pane is still alive but dont intend that they foil been abducted by space aliens? stem TO EXAMPLE 1.3.1 When we first get out the selective information in this example, it may seem as if the song contradict wiz another. For instance, we were told that 64 deal were surveyed, nonetheless at that transmit be 45 who believe that social disease is alive and 49 who believe that theyve been kidnapped by space aliens. Obviously, 45 + 49 is lots enceinte than 64, so it appears that the follow of tribe who responded to the survey is greater than the number of people who were surveyed. This app arnt contradiction in terms is resolved, however, when we take into banknote the circumstance that there are few people who blood into two categories (42 believe both of those things). A Venn diagram is effective in organizing the information in this type of problem. Since the data refers to two categories, we will use a two-circle diagram. allow U be the focalize of people who were surveyed. let E be the curry of people who believe that sexually transmitted disease is still alive.

Let A be the present of people who believe that they use up been abducted by space aliens. consequently we pull in the following Venn diagram showing the relationship in the midst of dos E, A and U: We are told that there are 42 people who believe both of these things. This gist that in the area of the diagram where distinguish E intersects set A, we have 42 people: We are to a fault told that 45 believe that Elvis is still alive. This means that set E must keep back a total of 45 people. We have already determined 42 people in one region of set E, so we must transmit 3 people in the other region of set E: We are alike told that 49 believe that they have been abducted by space aliens. This means that set...If you want to get a full essay, order it on our website: Orderessay
