MA 120: Finite Mathematics and Linear Modeling

When a jury decides whether or not a defendant is guilty, do they collectively use primarily inductive reasoning, deductive reasoning, or an equal amount of each? Write a paragraph supporting your answer. Use specific examples to support your thinking.

Identify two ways that you use estimation in your daily life. Discuss each of them in a paragraph and give examples.

Use the last digit of your phone number and create a Set A with that number of elements. Last digit is 3! Write your set using Roster Form. Identify the cardinality of your Set A using the correct notation. Identify the number of subsets and proper subsets of your Set A. Write a sentence or paragraph explaining the difference between the number of subsets and proper subsets.

4)

Create a Set B with your two favorite numbers. 1 and 7! Create a Set C with three initials of your name (if you don’t have three initials make one up, if you have more than three initials use your favorite three). (J.D.S)! Write your sets using Roster Form. Write the Cartesian Product of the two Sets C X B.

5)
Take a poll among 20 of your friends, family, business associates, or social media subscribers. Ask each person two question: A) Do you enjoy watching action movies? B) Do you enjoy watching documentary movies? Record your results in an organized list. See attachment A for an example. Complete the two-set Venn diagram template with numbers that represent your results. Label your diagram and each set. Be sure to include the number of people who may not enjoy either of those types of movies.

You can copy and paste the Venn Diagram outline below into your document and resize it as you need.
