The teacher in your classroom surveys her 30 students in an attempt to help them understand Venn Diagrams in the most complex form, when there are 3 counting options. She asks all the people wearing red shirts to stand up, 8 people stand. She asks them to sit down. Then she asks all those wearing blue pants to stand, 24 stand up. She asks them to sit. Then she asks all the people wearing black shoes to stand, and 10 stand up. She asks them to sit. While asking these questions, she notices 3 people have stood up for all questions, 4 are wearing both red shirts and blue pants, 7 are wearing both blue pants and black shoes and finally, 5 are wearing both red shirts and black shoes. Draw a 3 circle VENN diagram, label what each area represents and CALCULATE numbers for each area (show all your calculations using proper mathematical and statistical form for full marks).
